MHT CET 2023 Physics question

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 pointCorrect
(D)The electrostatic potential is constant within and on the surface of a conductor.

Answer: (C)

Solution

In electrostatics the free charges in a conductor rearrange until the net field inside is zero. Hence (a) is true (any excess charge resides on the surface, by Gauss's law), (b) is true, and (d) is true because inside means is constant throughout the volume and surface. If the field just outside
