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) 7.10 MeV 

(b) 6.30 MeV

(c) 5.4 MeV 

(d) 0.73 MeV

Answer 1

Correct Option (d) 0.73 MeV

Explanation:

According to given data, mass of neutron and proton are equal which do not permit the breaking up of neutron and proton, But if we take standard mass of neutron as 1.6725 × 10^–27 kg. then
