Two particles move towards each other from rest under a mutual force of attraction. At the instant, when the speed of A is V, the speed of B is V/2. The speed of centre of mass of the system is

View answer and explanation

Correct option: D

zero

Option D is correct. Since the particles move under mutual attraction and start from rest, there are no external forces. Therefore, the velocity of the center of mass of the system is zero.
