Two particles of masses $m_1$ and $m_2$ $(m_1 > m_2)$, initially at rest, move towards each other under an inverse square law force of attraction. Pick out the correct statement about the centre of mass $(CM)$ of the system
The $CM$ moves towards $m_1$
The $CM$ moves towards $m_2$
The $CM$ remains at rest
The motion of $CM$ is accelerated
A small disc of radius $2\, cm$ is cut from a disc of radius $6\, cm$. If the distance between their centres is $3.2\, cm$, what is the shift in the centre of mass of the disc ....... $cm$.
