Q. Two particles A and B initially at rest move towards each other under a mutual force of attraction. At the instant when the velocity of A is v and that of B is 2v. The velocity of centre of mass of the system is

EAMCETEAMCET 2010

Solution:

Initially both particles were at rest so $ {{v}_{cm}}=0. $ As external force on the system is zero. Therefore velocity of centre of mass remain unaffected.
