Question

A thin circular ring of mass $M$ and radius $r$ is rotating about its axis with an angular speed $\omega$. Two particles having mass m each are now attached at diametrically opposite points. The angular speed of the ring will become :

Select the correct option:

$\omega \frac{M}{M+m}$

$\omega \frac{M+2 m}{M}$

$\omega \frac{M}{M+2 m}$

$\omega \frac{M-2 m}{M+2 m}$
