MCQ (Single Correct Answer)

-1

Consider a two particle system with particles having masses $${m_1}$$ and $${m_2}$$. If the first particle is pushed towards the center of mass through a distance $$d,$$ by what distance should the second particle is moved, so as to keep the center of mass at the same position?

$${{{m_2}} \over {{m_1}}}\,\,d$$

$${{{m_1}} \over {{m_1} + {m_2}}}d$$

$${{{m_1}} \over {{m_2}}}d$$

$$d$$

A thin circular ring of mass $$m$$ and radius $$R$$ is rotating about its axis with a constant angular velocity $$\omega $$. Two objects each of mass $$M$$ are attached gently to the opposite ends of a diameter of the ring. The ring now rotates with an angular velocity $$\omega ' = $$

$${{\omega \left( {m + 2M} \right)} \over m}$$

$${{\omega \left( {m - 2M} \right)} \over {\left( {m + 2M} \right)}}$$

$${{\omega m} \over {\left( {m + M} \right)}}$$

$${{\omega m} \over {\left( {m + 2M} \right)}}$$
