Assume that a neutron breaks into a proton and an electron. The energy released during this process is (Mass of neutron $$=1.6725 \times 10^{-27}$$ kg; mass of proton $$= 1.6725 \times 10^{-27}$$ kg; mass of electron $$= 9 \times 10^{-31}$$ kg)

A

$$0.73$$ MeV

B

$$7.10$$ MeV

C

$$6.30$$ MeV

D

$$5.4$$ MeV
