Question

Imagine you have a single dipole p located a distance z above an infinite grounded conducting plane. The dipole makes an angle of ? relative to the perpendicular to the plane. Find the torque on p due to the induced charge on the plane. Hint: the equivalent problem is that of a dipole p and its mirror image dipole pi, shown in (a) below, located a distance 2z from the real dipole. Now imagine orienting our axis along pi, so the situation looks like (b) to the right. Compute the torque on p from the E-field of its image dipole pi.
