How much energy is released when a neutron (rest mass 939.6 MeV/c²)decays into a proton (rest mass 938.3 MeV/c²),an electron (rest mass 0.511 MeV/c²)and an anti-electron neutrino (rest mass approximately zero)? A)789 keV B)1.81 MeV C)1.88 GeV D)None are correct.

Question

Quizplus · Accepted Answer

The energy released is the difference in rest mass energy between the initial and final particles: 939.6 MeV - (938.3 MeV + 0.511 MeV) = 0.789 MeV or 789 keV.
