Two point-charges `+2e and -2 e` are situated at a distance of `2.4 Å` from each other and constitude an electric dipole. This dipole is placed in a uniform electric field of `4.0 xx 10^(5) "Vm"^(-1)`. Calculate
(i) electric dipole moment,
(ii) potential energy of the dipole in equilibrium position,
(iii) work done in rotating the dipole through `180^(@)` from the equilibrium position.
