A condenser is charged to a potential difference of `120V` ,its energy is `10^(-5)` J.If the battery is there and the space between the plates is filled up with a dielectric medium `(varepsilon_(r)=5)`,its new energy is .

`10^(-5)J`

`2 xx 10^(-5)J`

`3 xx 10^(-5)J`

`5 xx 10^(-5)J`

Text Solution

Verified by Experts

The correct Answer is:

`E^(1) = E_(r ) xx E`
