When an electron and a positron meet at low speed in empty space, they annihilate each other to produce two 0.511 MeV gamma rays. What conservation law would be violated if they produced one gamma-ray with an energy of 1.02 MeV? (a) energy (b) momentum (c) charge (d) baryon number (e) electron-lepton number
