Question

What is potential energy of a dipole in an uniform electric field..?

Answer 1

The potential energy is -P*E*cos(theta) where P is the dipole moment, E is the electric field and theta is the angle dipole makes with the field.

Also in this case we take theta=90° as a point of zero potential energy(reference).

Else the actual formula is for the potential energy stored when dipole is taken from angle theta1 to angle theta2 , i.e., U (potential energy)= PE{ cos(theta1) -cos(theta2) }.
You can refer to ARIHANT JEE BOOKS
They have clear explanation on this concept.
