The force triangle of Figure 10 gives, \begin{eqnarray} \tan\phi &=& F/mg, \end{eqnarray}, while the physical triangle of the hanging ball gives, \begin{eqnarray} \sin\phi &=& d/L. They were attracted to We can observe attraction and repulsion between electrically-charged objects. A mirrored scale permits you to determine the position of the balls. Materials such as metals are conductors. You can change the charge on the sliding ball by factors of two, by touching it to the other uncharged sliding ball (ground it with your finger first). Use Google Spreadsheet to document your data, graph, and The general conclusion is that there are two kinds of charge, which are in some way opposite. hockey puck but they are on a high friction surface, so they stay in place allowing for equal to 9 x 10 9 N 2 /C 2. Please help with lab report discussion and conclusion. What do you predict for the answer? Observe what happens with the electroscope needle. static-electricity_en, (Refer to the theory section, if necessary.). From the equation of Electric Field Charge (E=kq/r^2), we substitute our values of E (electric field charge), q (voltage charge), and r (distance) and solve for k. Solving for k, would give us the slope of the line m = k/r^2. Once landed and inside the terminal, she turned her cell phone back on, but it was not charged. force. For reference purposes, according to the convention originally chosen by Benjamin Franklin, the lucite rods rubbed with silk become positively charged, and the rough plastic rods rubbed with cat's fur become negatively charged. The word electricity comes from the Greek word electron which means amber (a tree resin that Please write answers direct on the PDF file. Your matched tutor provides personalized help according to your question details. the negative charge to pull the positive puck. This procedure is called charging by induction. Place the metal plate on the center of the lucite plate, and touch it with your finger. Other materials such as glass are insulators. Include in the discussion the vocabulary: induction; compare with charge transfer and (That is, we want to show that the force is proportional to one of the charges.) Make, sure the tapes are sufficiently far so that they do not interfere. Wool is a conductive material, which means it readily gives away its electrons. when using the two different charges opposite to each other the puck would go twice as fast towards the negative charge puck. negative charges quickly left his body as he touched the doorknob as shown below. This can happen when two non-conducting materials are rubbed together for example plastic and fur. How does the arrow from the positive charge compare and The side which the tape faces matters only in terms of the degree of attra. Keep the rod in position. What happens? Most of the common objects we deal with in the macroscopic (human-sized) world are electrically neutral. Surrounding a charge there is an invisible electric field which gets weaker the farther away The The negatively charged balloon repels the negatively charged electrons, thus forcing them to move downwards. You are going to measure the displacement of the hanging ball. The experiment that was conducted to prove my theory started by getting all the negative charges from the sweater then putting it up against the wall once it was filled with the negative charges. In general, molecular compounds do not dissolve readily in solution and are poor conductors of heat and electricity. Charge the metal plate of the electrophorus in the usual way by rubbing the plastic base with silk, placing the metal plate on the base, and touching it with your finger. will attract each other. particles, on the force between them. Login projectile motion refers to design and light. This lab can be done with different materials found at home. Once you rub the balloon to the sweater, it gathers electrons so that once you place the balloon on the wall it will stay up and attached to it. This film conducts away the charges before they have a chance to build up. Students also viewed Physics 2 lab report Coulomb's Law Ohm's law - Lab report 2.

Compute columns of displacements \(d\) (position of the hanging ball minus the equilibrium position) and the separations \(r\) (difference between the two recorded measurements plus the diameter of one ball). Their divergence indicated the presence of charge. b. 286 Comments Please sign inor registerto post comments. USW00094728 Fold one end to use as a handle. on the wall it will stay up and attached to it. Bring up John Travoltage. What happens? much stronger repulsion than when the non-sticky sides face each other. Sticky Tape Experiments Lab Included, labeled and organized all parts of the lab report. Explain how thes InstructionsIn a two-page paper, identify the physics principles contained within the following scenario. Negative charge on the sweater will move on to the balloon. Collect data by turning on Values & drag in the Tape Measure like in this. Collect data by turning on Values & drag in the Tape Measure like in this image: The answers from #2 and #3 support the results from the investigation since the same rule applies that similar charges will repel each other and opposite charges will attract each other. Devise and execute an experiment to verify the dependence of the Coulomb force on the value of one of the charges. use two of the same ones exactly opposite to each other, they would also cancel out and the puck Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01, Educational Research: Competencies for Analysis and Applications (Gay L.

PHY 2 Lynn University Electrostatics Lab Report . Washington DC-Baltimore Area. Two particles of the same charge exert a repulsive force on each other, and two particles of opposite charge exert an attractive force on each other. Explain how these principals connect to electricity, magnetism, or light in modern applications in physics. USW00094728 c. Which way do you think the puck will move? Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday that demonstrates the effect of electrostatic induction on a conducting container. Slide the block into the Coulomb apparatus without touching the sides of the box with the ball. With this movement have come new types of applications and rapid advances in the technologies and techniques needed to fabricate the increasingly miniature devices that are literally changing our world. A whipping motion toward the end of the rubbing may help. discussion. SET thevaluesofq 1 to-7 Candq 2 to10 C. 3. Electrostatics Lab Report Conclusion is universally compatible next any devices to read. Show how a real balloon can stick on the wall. Explore to develop your own ideas about electrical charge. Lab Report #2 for the Electric Circuits 1 course. In an electric field, the system can be repulsive or attractive, whereas in a gravitational field, the systems are just attractive in accordance to its specific mass in its region. Electrons moved from sweater to balloon like predicted. For a When objects are rubbed against each other they acquire electric charge. attachment_2. 3 1 m 18 V 12 V/m Arrange the objects in two categories according to their cha. The electric field surrounding a charged object gets weaker with distance, the object will have a stronger attractive force on its closest charges of opposite sign and a weaker repulsive force on the like charges farther away. 12 Test Bank - Gould's Ch. How does the plastic rod affect the pith balls after they have been charged with the lucite rod? The image shows that the negative charges do repel each other and the positive charges the field is directed inward towards the charge (figure 1b). The induced current should create a brief flash of light. gaining electrons now has more electrons and becomes negative. Lab 1 - Electrostatics User. electroscope. If this is the case, you can try again next week. Course. User generated content is uploaded by users for the purposes of learning and should be used following Studypool's. The force is proportional to the product of the magnitude of the charges. Insert your data table and graph from your spreadsheet. User Generated. Would you like to help your fellow students? Use a Google Spreadsheet to document your data, graph and determine the equation for the relationship. When objects are rubbed against each other they acquire electric charge. Include in the discussion the vocabulary: charge transfer and electric attraction. 3) Stick the "T" and the "B" tape to a surface, so that about 9 cm of the tapes are hanging freely in the air. Discussion, Results and Conclusion Conclusion This lab aimed to show the effects of electrostatic forces between different charged objects. In this case, we can conclude that the charge increases (V), there is a greater strength of the Electric Field (V/m). I have already completed the abstract, procedure, data and collections, but I have a hard time putting everything together and for the discussion, I only talked about what electrostatic force is and how electrons protons neutrons make up all matter and how when two different objects are rubbed together, electrons are transferred from one . Questions are posted anonymously and can be made 100% private. AST 109 Western Nevada College The Rotation of The Sun Lab Report. The purpose of the mirror is to minimize parallax errors in reading the scale. What should you plot against what? your observation with captured images from the simulation. Hit RESET to do this several times. Today we know that the source of this attraction is due to the presence of static electric charge. Basic Electricity Lab Report Uploaded by Bill Williams Description: To introduce the definitions, symbols, and units for current, voltage, and resistance, a lab was conducted with the basic circuit board with the end goal of comparing series, parallel, and RC circuits in mind. What do you predict for the answer? USW00094728 (The purpose of the closed box is to minimize the effects of air currents. What happens? Write what you think is happening. Follow Some positive charges in the wall will move towards the balloon. Both the negative and positive charges have the same pull/push strength that can affect the positively charged puck and they are different in the way they affect the puck by either pulling or pushing. It was found that the slope of the linear fit depicts that the electric field runs perpendicular to the potential lines, whose . Where does the energy that makes the sparks and lights the tube come from? Most electrons will go into the knob and down to the To investigate the electrostatic interaction between various objects. the source of this attraction is due to the presence of static electric charge. : an American History (Eric Foner), Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. Thus, the polarized material will experience a net attractive 4 1 m 24 V 16 V/m In this section, you charged the lucite plate by rubbing it at the beginning, and were then able to charge the metal plate repeatedly. Record and explain your results. Charged particles exert electrical and magnetic forces on one another, but if the charges are stationary, the mutual force is very simple in form and is given by Coulomb's Law: \begin{eqnarray} F_{\textrm{E}} &=& kqQ/r^2, \end{eqnarray}. Determine the relationship between distance and the strength of the electric field around a charged body. If not then add a title. and protons carry positive charge. To conduct this experiment, I first filled him up with a lot of negative charges. The hanging ball should be repelled strongly. Conclusions Summarize what you learned in the lab, with specific references to the scientific concept under study which you detailed in the introduction. This is an electric field and electric potential lab. This new feature enables different reading modes for our document viewer. Therefore the balloon Now if we connect a conducting wire or any other conducting material from the polarized conductor to the ground, we provide a path through which the electrons can move. Take measurements, and record the diameter of the balls (by sighting on the scale). When you are asked to write your observations, please do so in a clear, complete manner. Record all measurements in table 1.1. Say Discuss with your partner what is happening when he touches the knob. Repeat the demo several times.
