NDA 2017 Physics question

A positive charge is placed at the centre of a hollow metallic sphere of inner radius and outer radius . The electric field at a distance from the centre is denoted by . In this regard, which one of the following statements is correct ?

(A) for Correct
(B) for
(C) for
(D) for

Answer: (A)

Solution

In electrostatic equilibrium the electric field inside the material of a conductor is zero. The region is the metal of the shell, so there (the charge induces on
