NEET Physics Impulse & Momentum Assertion Reason Question
Assertion (A): The total momentum of a system remains conserved if no external force acts on it.
Reason (R): The forces within the system can change the momentum of individual bodies but not the total momentum of the system.
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
According to the law of conservation of momentum, in an isolated system with no external force, the total momentum is conserved. Forces within the system affect individual bodies but not the total momentum.
