Electric Potential & Equipotentials

A conducting sphere of radius R is given a charge Q. The electric potential and the electric field at the centre of the sphere rrespectively are

Show answer and solution

Answer: (b)

Inside a conductor $E = 0$ , so the field at the centre is zero.
Conductor is equipotential: $V_{\text{centre}} = \frac{Q}{4\pi\varepsilon_0 R}$
So the answer is (b) $\frac{Q}{4\pi\varepsilon_0 R}$ and zero.
