Consider a two particle system with 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?

  • A

    $d$

  • B

    $\left( {\frac{{{m_2}}}{{{m_1}}}} \right)d$

  • C

    $\left( {\frac{{{m_2}}}{{{m_1} + {m_2}}}} \right)d$

  • D

    $\left( {\frac{{{m_1}}}{{{m_2}}}} \right)d$

A smooth uniform rod of length $L$ and mass $M$ has two identical beads of negligible size, each of mass $m$ , which can slide freely along the rod. Initially the two beads are at the centre of the rod and the system is rotating with angular velocity $\omega _0$ about its axis perpendicular to the rod and passing through its mid-point (see figure). There are no external forces. When the beads reach the ends of the rod, the angular velocity of the system is
