NEET Physics Mass-Energy Relation Assertion Reason Question
Assertion (A): The mass of a nucleus is always less than the sum of the masses of its constituent protons and neutrons. | Reason (R): The mass defect is the difference between the mass of a nucleus and the total mass of its individual nucleons, and it results in the release of energy according to the mass-energy relation.
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 NCERT context explains that the nuclear mass is less than the total mass of its constituents due to the mass defect, which is related to energy release as per the mass-energy relation.
