STATEMENT-1: A parallel plate capacitor is charged by a battery. The battery is then disconnected. If the distance the plates is increased, the enegry strored in the capacitor will decrease.
STATEMENT-2: Work has to be done to increase the separation between the plates of a charged capacitor.

Options

A. Statement -1 si Ture, Statement -2 is True, Statement -2 is a correct explanation for Statement -1.
B. Statement-1 is True, Statement-2 is True, Statement-2 is Not a correct explanation for Statement-1.
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Answer

D

Explanation

The correct choice is `(D)`. The charge `Q` remains uncharged as the battery is disconnected. The capacitance `C` decreases if the separation between the plates s increased. Now, enegry stored `U = Q^(2)//2C`. Since `Q` remains the same and `C` is decreased, `U` will increases.
