Question

In a head-on collision of an electron of kinetic energy of 2.044 MeV with a positron at rest, the two particles are replaced by two photons of equal energy. If each photon is traveling at an angles θ with respect to the electron’s direction of motion, What is the energy E, momentum p (you can leave the answer in terms of c) and angle of θ of each photon? (For electron and positron mc2 = 0.511 MeV)

Answer #1

An electron and an antielectron (positron) each have a rest
energy of 0.511 MeV , or approximately 8.2×10-14 J .
When an electron and a positron are both stationary and located
next to each other during an annihilation process, their mass
energy converts to electromagnetic energy released as photons,
electromagnetic particles that have momentum but no mass and that
travel at the speed of light. What is the minimum number of photons
that could be released, and how much energy...

An electron has a kinetic energy K of 1 MeV and is incident on a
proton at rest in the laboratory. Calculate the speed of the CMS
