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

`(CV^2)/(2d)`

B

`(CV^2)/(d)`

C

`(C^2V^2)/(2d^2)`

D

`(C^2V^2)/(2d^2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Force of attraction between the plates
`F=q^2/(2Aepsilon_0) ` , where q = CV and `C=(epsilon_0A)/d`
`F=(C^2V^2)/(2Cd)= (CV^2)/(2d)`
