Physics-Mass-Energy Relation
NEET Physics Mass-Energy Relation Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): The unification of mass and energy conservation laws is crucial in understanding nuclear physics. | Reason (R): The principle of mass-energy equivalence, E = mc², implies the mass of a nucleus decreases when energy is released in nuclear reactions.
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 assertion and reason are both supported by the NCERT context, which describes the unified law of conservation of mass and energy as central to nuclear physics, evidenced by the mass-energy equivalence.
