1.	Two objects which are initally at rest, move towards each other under the action of their internal attraction. If their speeds are 4 v and 2 v at any instant, then the speed of centre of mass of the system will be
Answer» 2v ZERO v 1.5v Solution :As INITIALLY both the particles were at rest, THEREFORE, VELOCITY of the center of mass were. Zero. And no external force acting on the system. So velocity remains constant (Zero).
