A capacitor \( \mathrm{C} \) is charged to a potential difference \( \mathrm{V} \) and battery is disconnected. Now if the capacitor plates are \( b \). ought close slowly by some distance :
\( P \)
(A) some +ve work is done by external agent (B) energy of capacitor will decrease
(C) energy of capacitor will increase
(D) none of the above
