Which of the following statements is 'WRONG' for the conductors? (a) In static situation, the interior of conductor can have no charge. (b) The net electrostatic field is zero in the interior of a conductor. (c) The electrostatic field just outside the surface of charged conductor must be tangential to the surface at any point. (d) The electrostatic potential is constant within and on the surface of a conductor.

Answer: (c). (a) True: any net charge sits on the surface in the static case. (b) True: E = 0 inside, otherwise free charges would move. (c) Wrong: the field just outside is normal to the surface, not tangential. (d) True: E = 0 inside means V is constant throughout the conductor. So the answer is (c).

Electric Flux & Gauss's Law

Which of the following statements is 'WRONG' for the conductors?

Show answer and solution

Answer: (c)

(a) True: any net charge sits on the surface in the static case.
(b) True: $E = 0$ inside, otherwise free charges would move.
(c) Wrong: the field just outside is normal to the surface, not tangential.
(d) True: $E = 0$ inside means $V$ is constant throughout the conductor.
So the answer is (c).
