  • question_answer  Can two equipotential surfaces intersect each other? Justify your answer.

    Answer:

    No, two equipotential surfaces cannot intersect each other, because
    (i) two normals can be drawn at intersecting point on two surfaces which give two directions of electric field at the same point which is impossible.
    (ii) also two values of potential at the same point is not possible.
