Solution


Q.

Nucleus A having Z = 17 and equal number of protons and neutrons has 1.2 MeV binding energy per nucleon. Another nucleus B of Z = 12 has total 26 nucleons and 1.8 MeV binding energy per nucleon. The difference of binding energy of B and A will be ______ MeV.                 [2023]

Ans.

(6)

For A mass number =34

Total binding energy=1.2×34=40.8 MeV

For B mass number =26

Total binding energy=1.8×26 MeV=46.8 MeV

Difference of BE=6 MeV
