Physics-Mass-Energy Relation
NEET Physics Mass-Energy Relation Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): The mass of a nucleus is always less than the sum of the masses of its individual nucleons. | Reason (R): This mass difference, known as mass defect, is due to the nuclear binding energy that holds the nucleus together.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
The mass defect arises because the nuclear binding energy causes the nucleus to have less mass than the sum of its nucleons, as explained by the mass-energy relation.
