An electron of 1 MeV kinetic energy and a positron of 1 MeV kinetic energy have a head on collision (same velocity but in the opposite direction). After the annihilation, the electron and the positron disappear, and a pair of gammy rays is created. (a) Should this pair of gammy rays have the same kinetic energy always? Why? Yes, because energy is conserved. (b) If they have the same energy, what is the energy of each gamma ray? (c) What is the momentum of the each gamma ray? The unit of your answer may contain the speed of light c.
