Electrostatics

The potential energies associated with four
orientations of an electric dipole in an electric
field are

(i) \(-5U_0\) (ii) \(-7U_0\) (iii) \(3U_0\) (iv) \(5U_0\)

where \(U_0\) is positive. Rank the orientations according to the angle between the electric dipole moment p and electric field E, greatest first
