Question

Atomic mass of ${{^{13}}_{6}}C$ is 13.00335 amu and its ea-s number is 13.0. If 1 amu = 931 MeV, binding energy of the neutrons present in the nucleus is

• A. 0. 24 MeV
• B. 1. 44 MeV
• C. 1. 68 MeV
• D. 3, 12 MeV

Answer 1

Answer: (D)

3, 12 MeV

Answer 2

Binding energy of neutron $E=\Delta m\times 931\,MeV$ $\therefore$ $E=(13.00335-13)\times 931MeV$ $=3.12\,MeV$
