Question

A quantity of charge q is distributed uniformly throughout

Answer 1

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.
