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 ' = $

Question

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

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

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

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