The work done in increasing the potential of a capacitor from `V` volt to `2V ` volt is `W` Then, the work done in increasing the potential of the same capacitor from `2V` volt to `4V` volt will be.

A

`W`

B

`2W`

C

`4W`

D

`8W`

Text Solution

Verified by Experts

The correct Answer is:
C

`W=1/2C[(2V)^(2)-V_(2)]=-3/2CV^(2)`
`W'=1/2C[(2V)^(2)-(2V)^(2)=6CV^(2)`
`=(6xx2W)/3=4W`.
