Q. Consider the situation shown in the figure. The capacitor $A$ has a charge $q$ on it whereas $B$ 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) $2q$
Explanation

(a) The $\pm q$ charges appearing on the inner surfaces of $A,$ are bound charges. As $B$ is uncharged initially, as it is isolated, the charges on $A$ will not be affected on closing the switch $S.$ No charge will flow in to $B$
