What is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to e⃗
AleksandrR [38]

Electric potential energy of a dipole is given as

U = - P.E

U = - PE cos\theta

so change in the potential energy is given by

U_f - U_i = (-PEcos\theta_2)- (-PEcos\theta_1)

\Delta U = PE (cos\theta_1 - cos\theta_2)

here initially it was parallel to electric field while finally it is perpendicular to the electric field

so we have

\Delta U = PE(cos 0 - cos 90)

\Delta U = PE

so above is the change in potential energy of dipole
