Question

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

• A. $0.51\, MeV$
• B. $7.10\, MeV$
• C. $6.30\, MeV$
• D. $5.4\, MeV$

Answer 1

Answer: (A)

$0.51\, MeV$

Answer 2
