NEET Physics Centre of Mass MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Refer to the diagram where two masses, m1 and m2, are shown before and after an elastic collision. If m1 is heavier than m2, which of the following statements is true about the center of mass velocity after the collision?
A
The center of mass velocity remains the same as before the collision.
B
The center of mass velocity reverses direction.
C
The center of mass velocity increases.
D
The center of mass velocity decreases.
Correct Answer
Option A
Detailed Explanation
In an elastic collision, the total momentum and kinetic energy are conserved. Therefore, the velocity of the center of mass remains unchanged.
