Centre Of Mass Ques 10
Two particles of mass $1 kg$ and $3 kg$ move towards each other under their mutual force of attraction. No other force acts on them. When the relative velocity of approach of the two particles is $2 m / s$, their centre of mass has a velocity of $0 m / s$. When the relative velocity of approach becomes $3 m / s$, the velocity of the centre of mass is $0 m / s$.
