8:33 Done project. Supporting Activities (Provided only to support the development of your lab report - Do not submit the activities given here with the lab report. In this section one (1), you only have to produce the lab report covering all the headings of a lab report with data and calculations): Part 1: What is an equipotential line and how is this simulation related to work and energy? 1) Turn on "Show Numbers" 2) Place a positive 1 nano-coulomb charge near the center of the screen. 3) In the lower left of the screen is a meter for indicating electric potential, in volts, created by the charge that you introduced. Record the voltage and turn on "Plot". 4) This line is much like a line on a geologic topo map. Explain the similarity. 5) You are on the side of a hill with a topo map of the region. If you walked so that your trip follows a topo line you would be doing no work on your backpack. Why?. 6) If a second charge were placed on this line (don't do it), how much work is need to move it along the line? 7) Move the meter closer to the charge at the center of the screen. What is the new electric potential? Turn on plot again 8) Remember that electric potential is energy per charge (1 volt = 1 Joule/Coulomb). Is electric potential a vector or a scalar? 9) If a second positive charge were introduced and moved from the first equipotential line created to the second line (closer to the charge), would this involve positive or negative work? 13) Explain. 10) If the second positive charge were moved away from the first Positive charge, would this involve positive or negative work. 1 1) When energy was studied earlier in the year, a connection was found between kinetic energy, potential energy, positive work, and negative work. What is the connection? 12) Click on "Clear All" Part 2: What is the relationship between the electric potential at a point in space and the distance from an electric charge? 1) Place a positive 1 nano-coulomb charge an the screen. 2) Turn on "Show numbers" 3) Turn on "tape measure". 4) Use the tape measure to find and record the distance from the charge to the equipotential sensor. 5) Record the voltage as indicated on the equipotential sensor. 6) Change the location of the positive charge to at least six widely different distances from the equipotental sensor. Record the voltage reading and distance at each location. 7) Use "Excel" to plot these data sets. 8) What is the mathematical relation between these variables? 9) Click on "Clear All" Part 3: What are the characteristics of the electric field sensors? 1) Place a positive 1 nano-coulomb charge at the center of the screen. 2) Click on "Show Numbers. 3) Bring out an electric field senor. 4) What are electric field units? 5) Is the electric field a scalar or a vector? 6) To do its job, the electric field senor should have a charge. Why? 7) Does the field senor have a positive or negative charge? 8) Turn on the "Tape measure". 9) As you sample the electric field further and further from a charged object, you find that the field strength weakens. Do you think the E field vs. distance relation is an inverse relation, an inverse square, or some other power relation? Use the Electric field sensor and tape measure to collect data sets in order to answer this question. Include the "Excel" graph that you made in order to see if you hypothesis was correct.

Were you correct? * You only need to submit a comprehensive lab report for the section one (1). The questions given under the supporting activities are not necessary to be submitted with the lab report. If you have any questions regarding the answers to the above questions, you may contact the professor. Once you have completed each of the prior directions for Section One (1), save your work and move onto Section Two (2) Section Two (2): INSTRUCTIONS FOR COMPLETING SECTION TWO (2): 1. Answer the following question(s): 1. The two charges in the figure below are separated by d = 4.00 cm. (Let q) = -15.5 nC and q2 = 29.5 nc.) d 60.0 B (a) Find the electric potential at point A. (b) Find the electric potential at point B, which is halfway between the charges. Submit Section One (1) and Section Two (2) to the relevant dropbox within the course.

Therefore, the first step is to visit the following webpage: (You may use any of the following simulation links.) http:/phet.colorado.edu/simulations/sims.php?sim=Charges_and_Fields https:/phet.colorado.edu/sims/charges-and-fields/charges-and-fields_en.html The purpose of this webpage is to provide you with the simulation to complete this lab activity. This lab activity has two (2) sections. The purpose of each of these two (2) sections is to provide you with an opportunity to learn the principles of physics and apply them to solve relevant problems. Upon completion of these two (2) sections, you will be better prepared to tackle future physics problems and the examinations in this course (the midterm examination and the final examination). Section 1 requires you to produce a lab report and the section 2 requires you to answer questions. The second step is to scroll down to each of the two (2) sections and follow the instructions given in each section. Once you have completed each of the sections, move onto the third step. The third step is to ensure that you have completed all the relevant questions and sections for this lab activity, and then submit your work to the dropbox within the course. OBJECTIVES: Objectives At the end of this lab activity, the student Discuss electric potential and electric should be able to charge. At the end of this lab activity, the student Solve problems involving electric should be able to potential and electric charge. At the end of this lab activity, the student Devise experiments and write satisfactory should be able to laboratory reports SECTION ONE (1) - INSTRUCTIONS FOR COMPLETING SECTION ONE (1): 1. Click on "Run Now" within the simulation. The link to the simulation was provided in the "DETAILED DIRECTIONS FOR LAB ACTIVITY COMPLETION." 2. Run the simulation. 3. Use the simulation to develop the laboratory report. 4. Ensure that you have completed the lab report, and then move to "Section Two (2)." DIRECTIONS TO DEVELOP LAB REPORT: 1. For this section, you must write a laboratory report of an experiment to establish a relationship between electric potential and the distance from the electric charge. Use the simulation to conduct your experiment and gather data for this section. Under the heading, "Supporting Activities," some possible activities are given (These activities are to give you an understanding of the experiments you can use for your lab report). 2. Follow the general outline of a lab report as provided in the link below: http://www.utm.edu/staff/cerkal/report.html 3. Remember to show your calculations where necessary. These laboratory reports will prepare you to do well in the future lab activities and in the project.
