Answer:
Explanation:
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 q1 be the charge on the outer surface of sphere
Since outer sphere is earthed potential on it is zero . Therefore
14π∈0(q2R−q2R+q12R)=0
q|=0.
