Assume that a neutron breaks into a proton and electron. The energy released during this process is (Mass of neutron = 1.6725 × 10 - 27   K g = m a s s   o f   p r o t o n = 1.6725 × 10 - 27   k g , mass of electron = 9 × 10 - 31   K g ) ,

Options

  1. A0.73 MeV
  2. B7.10 MeV
  3. C6.30 MeV
  4. D5.4 MeV

Correct answer

A. 0.73 MeV

Step-by-step solution

∆ m = m p + m e - m n Energy released = ∆ m × c 2
