Question

Two objects are on a table. One is negatively charged and the other is electrically neutral. What happens?

Select one:

a. Since the second object is neutral, the charged object has no effect.

b. The positive charges in the neutral object are attracted to the negatively charged object, so they move to same side of the neutral object as the charged object. Then, the two objects experience an attractive force.

c. The negative charges in the neutral object are repulsed by the negatively charged object, so they move to the opposite side of the neutral object away from the charged object. Then, the two objects experience an attractive force.

d. The negative charges in the neutral object are attracted by the negatively charged object, so they move to the same side of the neutral object toward the charged object. Then, the two objects experience a repulsive force.

Explanation / Answer

c. The negative charges in the neutral object are repulsed by the negatively charged object, so they move to the opposite side of the neutral object away from the charged object. Then, the two objects experience an attractive force.

A good example for this one this one is placing a rubbing comb near a paper piece.
