Question

A parallel plate air capacitor has capacity C , distance of separation between plates is d and potential difference V is applied between the plates. The force of attraction between the plates of the capacitor is, C V 2 2 d ., C V 2 d ., C 2 V 2 2 d 2 ., C 2 V 2 2 d .

MARKS App · Accepted Answer

Attraction force between the plates, F = q 2 2 A ε 0 where q = C V and C = ε 0 A d ⇒ F = C 2 V 2 2 C d = C V 2 2 d
