Follow the instructions on page 7, using your Pie Plate Demonstrator to answer the following questions. In this experiment, we assume the foam plate has a positive charge when rubbed with paper towels. Lift the pan away from the charged plate using the styrofoam cup. Briefly touch the rim of the pan to neutralize it. Place the neutralized pan on the plate and observe the tape rise. When the pan is on the plate, the rim of the plate has a (positive charge/negative charge). This means that (the pan base is negatively charged/ the pan base is positively charged) because the net charge on the pan is (positive/negative/zero). You know that this must be the case because as you lift the pan with the cup away from the plate, the tape on the rim goes down. This indicates that there is (a net charge on the rim/no net charge on the rim), therefore the pan is (positively charged/negatively charge/neutral/charged, but not able to determine the sign).
