Conisder the istuation shown in the figure. The capacitor A has a charge q on it whereas B is unchanged. The charge appearing on the capacitor B a long time after the switch is closed is

A

(a) zero

B

(b) `q//2`

C

(c) `q`

D

(d) 2q

Text Solution

Verified by Experts

The correct Answer is:
A
When S is closed, there will be no shifting of negative charge from plate A to B as the charge-q is held by the charge +q. Neither there will be any shifting of charge form B to A.
