NEET Physics Mass-Energy Relation Assertion Reason Question
Assertion (A): The mass defect of a nucleus can be converted into binding energy using Einstein's mass-energy relation.
Reason (R): The binding energy per nucleon is constant across all nuclei.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The assertion is true because the mass defect is converted into binding energy using the relation ΔEb = ΔM c². The reason is false as the binding energy per nucleon is nearly constant only in the mass number range A = 30 to 170, not across all nuclei.
