Suppose two charges,one positive and one negative,are separated by a distance d.Where can two equipotential surfaces at different potentials intersect in the region near the charges?
A) halfway between the charges if the charges have the same magnitude
B) closer to the smaller negative charge than the larger positive charge if the charges are not equal
C) Equipotential surfaces at different potentials cannot intersect.
D) closer to the smaller positive charge than the larger negative charge if the charges are not equal

This is because equipotential surfaces are surfaces of constant potential, and if two different potentials intersect, it means there is a point on one surface that has two different potentials, which is not possible. The equipotential surfaces can only get closer together as they approach the charges, but they cannot intersect.
