Electric Flux & Gauss's Law

The electric field at a distance $\frac{3R}{2}$ from the centre of a charged conducting spherical shell of radius R is E. The electric field at a distance $\frac{R}{2}$ from the centre of the sphere is

Show answer and solution

Answer: (a)

All charge of a conducting shell lies on its surface.
At $r = \frac{R}{2} < R$ the enclosed charge is zero, so $E = 0$ .
So the answer is (a) zero.
