In a parallel plate capacitor of capacit...

In a parallel plate capacitor of capacitance `C`, a metal sheet is inserted between the plates, parallel to them. If the thickness of the sheet is half of the separation between the plates. The capacitance will be

A

`C//2`

B

`3C//4`

C

4C

D

2C

Text Solution

Verified by Experts

The correct Answer is:
D
`C.=(epsilon_0A)/([d-t+t/k])=(epsilon_0A)/([d-d/2+t/oo])=2C`
`k rarroo` for conductor.
