Initial position of centre of mass ...(i)
If the particles of mass is pushed towards the centre of mass of the system through distance and to keep the centre of mass at the original position let second particle be displaced through distance away from the centre of mass
Now …(ii)
Equating (i) and (ii)
By solving
Negative sign shows that particle should be displaced towards the centre of mass of the system
