`A, B, C, D, E,` and `F` are conducting plates each of area `A`, and any two consecutive plates are separated by a distance `d`, The energy in system after the switch `S` is closed is`
.

A

`(3epsilon_(0)A)/(2d)V^(2)`

B

`(5epsilon_(0)A)/(12d)V^(2)`

C

`(3epsilon_(0)A)/(2d)V^(2)`

D

`(epsilon_(0)A)/(d)V^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`V_(A)=V_(2)` and `V_(C)=V_(E)`
Net energy stored is `U=1/2CV^(2)`
`C=(epsilon_(0)A)/d` ("For" `EF`)
