Solving a problem in physics section 44 point 26 quantu

26. In the collision the electron and positron is their annihilation, in which an electron-positron pair turns into two γ-photon pairs and the energy goes into the energy of the photons. Determine the energy of each of the photons arising, assuming that the kinetic energy of the electron and positron before the collision is negligible.
