*Write the electric field of a dipole in vector notation. Using the result of Problem 3, find the potential energy of a dipole of moment d in the field of another dipole of moment d'. (Take ' at the origin and d at position r.) Find the forces and couples acting between the dipoles if they are placed on the z-axis and (a) both are pointing in the 2- direction, (b) both are pointing in the z-direction, (c) d is in the z- direction, and d' in the x-direction, and (d) d is in the x-direction and d' in the y-direction.
