Consider a two-particle system with the particles having masses m_(1) and m_(2). If the first particle is pushed towards the centre of mass through a distance d. by what distance should the second particle be moved so as to keep the centre of mass at the same position?

Answer»

`d.=(m_(1))/(m_(2))d`
`d.=(m_(2))/(m_(1))d`
`d.=(m_(1)+m_(2))/(m_(1))d`
`d.=(m_(1)-m_(2))/(m_(1))d`
