The mass of proton is 1.0073u1.0073 u and that of neutron is 1.0087u(u=1.0087 u(u= atomic mass unit). The binding energy of 24He{ }_2^4 \mathrm{He} is: (Given helium nucleus mass ≈4.0015\approx 4.0015 u)

Options

  1. A0.0305 J0.0305 \mathrm{~J}
  2. B0.0305erg0.0305 \mathrm{erg}
  3. C28.4MeV28.4 \mathrm{Me} \mathrm{V}
  4. D0.061u0.061 \mathrm{u}

Correct answer

C. 28.4MeV28.4 \mathrm{Me} \mathrm{V}

Step-by-step solution

BE=4m×931\mathrm{BE}=4 m \times 931 =[2(1.0087+1.0073)−4.0015]×=[2(1.0087+1.0073)-4.0015] \times 931 =28.4MeV=28.4 \mathrm{MeV}.
