    When an electric dipole of moment | vec(p) | = q xx 2a is held at an angle theta , with the direction of uniform external electric field vec(E) , a torque tau = pE sin theta acts on the dipole. This torque tries to align the electric dipole in the direction of the field. When vec(p) is along vec(E), theta^(@) , tau = pE sin 0^(@) = zero . The dipole is in stabel equilibrium. The energy possessed by the dipole by virtue of its particular position in the electric field is called potential energy of dipole. U = W = -pE (cos theta_(2) - cos theta_(1)) theta_(1) = 90^(@) is the position of zero potential energy. :. U = W = -pE (cos theta - cos 90^(@)) = -pE cos theta .
