Question

Figure shows a system of three concentric metal shells A, B and C with radii a, 2a and 3a respectively. Shell B is earthed and shell C is given a charge Q. Now if shell C is connected to shell A, then the final charge on the shell B, is equal to :
           

Options

A.
B.
C.
D.

Solution

         
From given conditions,
VA = VC and VB = 0
⇒VB  =    =  0
⇒  2Q + q1 + 3q2 = 0        ....(1)
Using VA = VC

⇒  q1  =  - 
Using it in (1), q2  =  -
