equipotential line curves a bit, you should try your best to draw a smoothly curving line. Be sure to label the equipotential line with the value of the potential along that line. At this point, your graph paper should probably look something like Figure 4 (but with a voltage for that line labeled). 6. Now, follow essentially the same procedure as outlined in steps 3-5 above for at least six more equipotential lines, each with a different value of the electric potential. Your goal is to have a reasonably accurate "map" of the equipotential lines throughout the region between and around the electrodes. 7. In another color of pen or pencil (if available), draw at least five electric field lines on your graph paper and be sure to draw arrows to indicate the direction of the electric field somewhere on each line. Analysis Q1. If we assume that the two electrodes in our experiment each have a static (non-changing) net charge on them, how could you use your plot to determine which electrode is more positively charged? Q2. Suppose you placed an electron (qe=-1.60 x 109 C) at a random point on one of your equipotential lines. How much work would it require to push that electron 10 cm, precisely along that equipotential line? Q3. Suppose you instead decide to move a single electron from the "positive" electrode to the other electrode. Does the amount of work required to push the electron depend upon what path you choose to go between the two electrodes? Why or why not? Q4. Now estimate (based on your actual data) how much work would be required to move an electron from the "positive" electrode to the other.
