Which of the following is not true for a perfect conductor?
- A Electric field inside a conductor is zero
- B The charge carried by a conductor is always uniformly distributed over the surface of the conductor irrespective of the shape of the conductor.
- C The surface of a conductor is an equipotential surface.
- D The electric field just outside a conductor is always perpendicular to the surface.
Answer & Solution
Correct Answer
(B) The charge carried by a conductor is always uniformly distributed over the surface of the conductor irrespective of the shape of the conductor.
Step-by-step Solution
Detailed explanation
For a perfect conductor in electrostatic equilibrium, the electric field inside the conductor is zero, which is a fundamental property. This implies that the potential is constant throughout the volume of the conductor, making the surface an equipotential surface. Consequently,…
