Suppose you charge two transparencies by rubbing and then hold them near each other but not touching. Regarding the electric and magnetic forces they exert on each other,
A) they will exert magnetic forces but not electric forces.
B) they will exert electric forces but not magnetic forces.
C) they will exert both electric and magnetic forces.
D) they will exert neither electric nor magnetic forces because neither object is moving.
E) they will exert neither electric nor magnetic forces because they are not in contact with each other.
