An electron-positron pair (rest mass of each particle = 0.51 MeV) is produced by a `gamma-`ray photon of energy 2.42MeV. The K.E. imparted to each of the charged particles shall be-

An electron-positron pair is produced when a gamma -ray photon of energy 2.36MeV passes close to a heavy nucleus. Find the kinetic energy carried by each particle produced, as well as the total energy with each.

An electron - positron pair annihilates at rest to produce gamma -rays. Calculate the energy produced in MeV if the rest mass of electron is 9.1xx10^(-31)kg .
