Question

find electric potential energy of an electric dipole moment placed in uniform electric field​

Answer 1

Answer:

Potential energy of dipole in uniform electric field.

τ=p×E

work done in rotating dipole by small angle

dw=τdθ

=−pεsinθdθ

The change in potential energy 

dU=−dW=pEsinθdθ

If θ→90o to θo

U(θ)−U(90o)=∫90o0oPεsinθdθ

=Pε[−cosθ]900

=−P.E

So

U(θ)=−P.E
