Question

An electric dipole consisting of charges + q and – q separated by a distance L is in stable equilibrium in a uniform electric field . The electrostatic potential energy of the dipole is

Answer 1

Answer:

The electrostatic potential energy of the dipole is -qLE .

Given :

An electric dipole consisting of charges +q and - q .

Separation between these two charges is L .

We need to find the electrostatic potential energy of the dipole .

We know electrostatic potential energy of the dipole is given by :

P=-pEP=−pE ...( 1 )

Here , p is electric dipole defined by product of charge and distance between them .

p = qL .

Putting value of p in equation 1 ,

We get , P=-qLEP=−qLE

Hence , this is the required solution
