NEET Physics Centre of Mass Assertion Reason Question
Assertion (A): The center of mass of an isolated system of particles moves with a constant velocity.
Reason (R): The external force acting on the system is zero.
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
In an isolated system, the net external force is zero, which implies that the velocity of the center of mass remains constant as per Newton's first law.
