nucleus is 0.042 u less than the sum of the masses of all its nucleons. The binding energy per nucleon of nucleus is nearlyOptions
A.46 MeV
B.5.6 MeV
C.3.9 MeV
D.23 MeV
Solution
For nucleus,
Mass defect, ᐃM = 0.042 u
∵ 1 u = 931.5 MeV/c2
∴ ᐃM = 0.042 × 931.5 Mev/c2
= 39.1 MeV/c2
Binding energy, Eb = ᐃMc2
c2 = 39.1 MeV
Binding energy per nucleon, Ebn =
