(C) The system consists of two particles moving under the influence of internal forces only.According to the law of conservation of momentum,if the net external force acting on a system is zero,the velocity of the centre of mass remains constant.Initially,both particles are at rest,so the initial velocity of the centre of mass is $v_{cm, initial} = 0$.Since no external force acts on the system,the velocity of the centre of mass remains $v_{cm} = 0$ at any instant.

Two particles which are initially at rest,move towards each other under the action of their internal attraction. If their speeds are $v$ and $2v$ at any instant,then the speed of the centre of mass of the system will be
