    Consider the situation shown in the figure. The capacitor A has a charge q on it whereas vB is uncharged. The charge appearing on the capacitor B a long time after the switch is closed is

    A) zero                              

    B) \[q/2\]

    C) \[q\]                 

    D)        \[2q\]

    Correct Answer: A

    Solution :

    [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 from B to A.
