Question

Which of the following is correct for energy of a dipole in a uniform electric field? a. It only alligns itself along the electric field b. Potential energy remains constant c. Dipole alligns along electric field and its energy decreases d. Energy is gained ​

Answer 1

Answer:

The potential energy of electric dipole is,

U=−P.E=−PEcosθ

where E=  uniform electric field

             P=Electric dipole   

           θ= angle between field and dipole

The potential energy is minimum when θ=0

U=−PE

The correct option A.
