B. Point Charges. Hit the lower right reset, and set up + and - point charges exactly as in the very upper figure. We will move the meter's cross hairs to points that may not be on intersections of major grid lines-do the best you can. Drawn in white with +'s is where you will move the meter's crosshairs each time, for each next data point. 1 5. + +6. 43. Record the point 1 voltage, and move the meter to points 2-8. Record voltages to nearest tenth, below. 1. V. 2. V. 3. V. 4. V. 5. V. 6. V. 7._ V. 8. V. (the order of the points circles the + charge) These are very sensitive, slight cross hair changes cannot be avoided. The second figure to the right has the theoretical equipotential lines from the lecture (dashed in green). Is our data similar to the theoretical equipotential lines? Yes/No.mp5://pnet.0010raoo.eaw$1mStml/cnarges-ana-I1elc151latesucnarg and-elds_en.html Electric Charges, Fields and Potentials Open the Simulation. Click on Voltage, Values and Grid boxes on upper-right. We will start off by setting up, just as last week. However, Voltages has been clicked on, putting colors around each charge. The intensity of the color corresponds to the potential around each charge. The purpose of the lab is to verify the equipotential lines, and calculations, from the lecture. I I - . I' _ ........ The grid, has major and minor lines; the lower-right arrow shows 2 major lines are l m apart. Pull the red + charge up 4 major lines, and then 3 major lines to the left. You will immediately see its B eld lines. Then pull the blue charge up 4 major lines, and then 6 major lines to the right of the red charge. This puts them 6 major lines apart, or 3 m. Be certain to place them exactly as is shown. Also the nano prex is n = 1E9. We will begin calculating E = 9>
