Physics-Mass-Energy Relation

NEET Physics Mass-Energy Relation MCQ Question

Type: MCQ-diagram based-Medium-Class 12

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?

Question diagram
A

ΔM is directly proportional to the total number of nucleons.

B

ΔM is inversely proportional to the binding energy per nucleon.

C

ΔM is independent of the mass number A.

D

ΔM decreases as the number of protons increases.

Correct Answer

Option A

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.
