Assume that a neutron breaks into a proton and an electron. The energy released during this process is : (mass of neutron , Mass of proton , mass of electron )                                   [AIEEE 2012]

A)             0.73 MeV

B) 7.10 MeV

C)             6.30 MeV

D) 5.4 MeV

Correct Answer: A

Solution :

[a]

Energy

MeV

Which is nearly equal to 0.73 Mev but as energy will be required. since mass is increasing so answer  Mev either [a] or bonus.
