An electric field of `1000 V//m` is applied to an electric dipole at angle of `45^(@)`. The value of electric dipole moment is `10^(-29) C.m` .What is the potential energy of the electric dipole ?

`-10xx10^(-29)J`

`-7xx10^(-27)J`

`-20xx10^(-18)J`

`-9xx10^(-20)J`

Text Solution

Verified by Experts

The correct Answer is:

`U=-vecP vec E, U=-10^(-29) times 1000 times 1/sqrt2 or U=-7 times 10^-27 g`
