In a parallel plate capacitor of capacitance C, a metal sheet is inserted between the plates, parallel to them. The thickness of the sheet is half of the separation between the plates. The capacitance now becomes

A

C/4

B

C/2

C

2C

D

4C

Text Solution

Verified by Experts

The correct Answer is:
C
As electric field inside the metal plate is zero d becomes d/2. Hence c becomes twice
