The energy density in an electric field ...

The energy density in an electric field of intensity 100 V/m is

A

`8.85xx10^(-8)J//m^(3)`

B

`4.425xx10^(-8)J//m^(3)`

C

`8.85xx10^(-6)J//m^(3)`

D

`4.425xx10^(-10)J//m^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
Energy density `=(1)/(2)epsi_(0)KE^(2)`
`=(1)/(2)xx8.85xx10^(-12)xx1xx10^(4)=4.425xx10^(-8)(J)/(m^(3))`
