The electrostatic energy stored in the 1 litre volume of air when it is placed in uniform electric field of intensity `10^(3)V//m` is

A

`44.25xx10^(-9) J`

B

`4.425xx10^(-9) J`

C

`44.25xx10^(-6) J`

D

`44.25xx10^(-5) J`

Text Solution

Verified by Experts

The correct Answer is:
B
Energy = `1/2in_(0)kE^(2)xx"volume"`
`=(8.85xx10^(-12)xx1xx10^(6)xx10^(-3))/2`
`=4.425xx10^(-9)J`
