Question
Charge q on a small conducting sphere S1 is placed inside a large hollow metallic sphere S2 having a charge Q as shown in figure. The charge on S1 after it is connected to S2 is :
Options
A.Q - q
B.qQ/2
C.(Q + q)/2
D.zero
Solution
For potential difference to be zero between S1 & S2, electric field between the conducting spheres S1 & S2 must be zero. So charge on S1 must be zero.
