If outer surface is earthed its charge becomes 0.

Q. A charge $q$ is distributed uniformly on the surface of a sphere of radius $R$ . It is covered by a concentric hollow conducting sphere of radius $2 R$ . Charge on the outer surface of the hollow sphere will be, if it is earthed

$\frac{q}{2}$

$2 q$

$4 q$

Zero

If outer surface is earthed its charge becomes $0$ .
