NEET Physics Mass-Energy Relation MCQ Question
In the diagram shown above, if the binding energy per nucleon is nearly constant at 8 MeV/nucleon for nuclei with mass numbers A = 30 to 170, which statement about the mass defect ΔM is correct?
ΔM is directly proportional to the total number of nucleons.
ΔM is inversely proportional to the binding energy per nucleon.
ΔM is independent of the mass number A.
ΔM decreases as the number of protons increases.
Correct Answer
Detailed Explanation
As binding energy per nucleon is constant, the total binding energy (and thus mass defect ΔM) increases with the total number of nucleons.
