Identify the correct properties of equipotential surfaces among the following.

(A) No work is done in moving a test charge over an equipotential surface.
(B) Electric field is always normal to the equipotential surface at every point.
(C) Equipotential surfaces are closer together in the regions of the strong electric field and farther apart in the regions of the weak electric field.
(D) No two equipotential surfaces can intersect each other.

Choose the correct answer from the options given below:

(A), (B), (C) and (D)

The correct answer is Option (3) → (A), (B), (C) and (D)

(A) True: Work done $W = q \Delta V = 0$ on an equipotential surface.

(B) True: Electric field is always normal to equipotential surface, otherwise work would be done.

(C) True: Stronger field implies greater potential gradient implies surfaces closer.

(D) True: Two equipotential surfaces cannot intersect, otherwise one point would have two potentials.

Correct properties: (A), (B), (C), (D)
