At this point, there is a movement of electrons. Electrons move____ . a. out of the aluminum plate into the ground (hand) b. into the aluminum plate from the ground (hand) c. into the aluminum plate from the Styrofoam d. out of the aluminum plate into the Styrofoam e. from the ground through the aluminum plate to theStyrofoam f. from the Styrofoam through the aluminum plate to theground g. .... nonsense! Elect rons do not move at all. A positively charged piece of Styrofoam is placed on the table.A neutral aluminum pie plate is brought near as shown below. Whileheld above the Styrofoam, the aluminum plate is touched (grounded).

Explanation / Answer

the previous answer is strange

Answer: B

Since the foam is not contacted to the aluminum plate, electronsdo NOT move between the foam and the aluminum (ruling out choicesc, d, e, and f). The presence of the positively charged foam platedraws electrons from ground to the aluminum plate. This is theprinciple of opposites attract.
