A 200kev electron ie an electron having kinetic energy of, Ask an Expert

Academics

A 200KeV electron (i.e., an electron having kinetic energy of 200KeV) collides with a 200KeV positron (a particle with opposite charge of electron but) moving in the opposite direction in a head-on collision. The electron-positron pair annihilate each other and emit two equal-energy photons. (a) Write the law of conservation of energy for this process putting in all appropriate values. (b) write the law of conservation of momentum for this process putting in all appropriate values.
