Two particles P and Q of mass 1 kg and 3 kg respectively start moving towards each other form rest under mutual attraction. What is the velocity of their center of mass ?

Text Solution

Verified by Experts

Given: Mass of particle P-1 kg
Mass of particle Q = 3 kg
Sol. Particles and forms a system. Here no external force is acting on the system,
We know that `M(d)/(dt)(V_(CM))=f`
means that, C.M. of an isolated system remains at rest when no extemal force is acting and internal forces do not change its center of mass.
