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. Force of attraction between the plates of the parallel plate air capacitor is (A) (C2 V2/2 d2) (B) (C2 V2/2 d) (C) (C V2/2 d) (D) (C V2/d)

Tardigrade Admin · Accepted Answer

Correct answer is (c) (C V2/2 d)

Q. A parallel plate air capacitor has capacity $C$ . Distance of separation between plates is $d$ and potential difference $V$ is applied between the plates. Force of attraction between the plates of the parallel plate air capacitor is

$\frac{C ^{2} V ^{2}}{2 d ^{2}}$

$\frac{C ^{2} V ^{2}}{2 d}$

$\frac{C V ^{2}}{2 d}$

$\frac{C V ^{2}}{d}$

Correct answer is (c) $\frac{C V ^{2}}{2 d}$
