The mass of proton is 1.0073 u and that of neutron is 1.0087 u(u= atomic mass unit). The binding energy of ₂^4 He is: (Given helium nucleus mass 4.0015 u)

Options

  1. A0.0305 ~J
  2. B0.0305 erg
  3. C28.4 Me V
  4. D0.061 u

Correct answer

C. 28.4 Me V

Step-by-step solution

BE =4 m 931=[2(1.0087+1.0073)-4.0015] 931 =28.4 MeV .
