Answer : (a) -q
Explanation :
The charge on the inner surface should be $\;-q\;,$ because if we draw a closed gaussion surface through the material of the hollow sphere the total charge encloses by this gaussion surface should be zero . Let $\;q_{1}\;$ be the charge on the outer surface of sphere
Since outer sphere is earthed potential on it is zero . Therefore
