A thin circular ring of mass M and radius r is rotating about its axis with an angular speed ω. Two particles, each of mass m, are now gently attached at diametrically opposite points. The angular speed of the ring becomes
1
\(\rm\left[\frac{M−2 m}{M+2 m}\right] \omega\)
2
\(\rm\left[\frac{M+2 m}{M}\right] \omega\)
3
\(\rm\left[\frac{M}{M+m}\right] \omega\)
4
\(\rm\left[\frac{M}{M+2 m}\right] \omega\)
