QAIPMT-2010-Ph-2061: NEET 2010 Physics - Class 12 AIPMT-2010-Ph-2061 Solution: The mass of a \(_3^7Li\) nucleus is 0.042 u less than the sum…
The mass of a nucleus is 0.042 u less than the sum of the masses of all its nucleons. The binding energy per nucleon of nucleus is nearly
Multiple Choice Options
- A 46 MeV
- B 5.6 MeV
- C 3.9 MeV
- D 23 MeV
Step-by-Step Verified Solution
For 3 7 L i nucleus,
Mass defect, _ M = 0.042 u
_ 1 u = 931.5 MeV/c 2
_ _ M = 0.042 _ 931.5 MeV/c 2
= 39.1 MeV/c 2
Number of nucleons in 3 7 L i is 7.
Binding energy per nucleon,
E bn = 39.1 7 = 5.6 MeV
