(a) Show that a classical oscillating electric dipole p with fields given by (9.18) radiates electromagnetic angular momentum to infinity at the rate

(b) What is the ratio of angular momentum radiated to energy radiated? Interpret.
(c) For a charge e rotating in the x-y plane at radius a and angular speed I?, show that there is only a z component of radiated angular momentum with magnitude dLz/dt = ??2k3??2/6I?N?0. What about a charge oscillating along the z axis?
(d) What are the results corresponding to parts a and b for magnetic dipole radiation?
