NEET Physics Centre of Mass Assertion Reason Question
Assertion (A): In an elastic collision involving two bodies, the total kinetic energy after the collision is equal to the total kinetic energy before the collision. | Reason (R): The center of mass of a system of particles moves as if all the mass of the system is concentrated at the center of mass and all external forces are applied there.
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
A is true because in an elastic collision, kinetic energy is conserved. R is true but does not explain A; it describes the motion of the center of mass, not energy conservation.
