The potential difference between the pla...

The potential difference between the plates of a parallel plate capacitor is 10V and separation is 5 cm. Find the energy density between plates. (`epsilon_0=10^(-11)`F/m)

`4xx10^(-7)"J/m"^3`

`5xx10^(-7)"J/m"^3`

`2xx10^(-7)"J/m"^3`

`3xx10^(-7)"J/m"^3`

Text Solution

Verified by Experts

The correct Answer is:

Energy density=`1/2epsilon_0 E^2`
`=1/2xx10^(-11)xx(10/(5xx10^(-2)))^2`
`=2xx10^(-7) "J/m"^3`
