A) \[\frac{M\omega }{2m}\]
B) \[\frac{2M\omega }{M}\]
C) \[\frac{(M+2m)}{M}\omega \]
D) \[\left( \frac{M\omega }{M+2\omega } \right)\]
Correct Answer: D
Solution :
\[{{I}_{1}}{{\omega }_{1}}={{I}_{2}}{{\omega }_{2}}\] \[\frac{M{{R}^{2}}}{2}\omega =\frac{1}{2}(M+2m){{R}^{2}}{{\omega }^{2}}\] \[{{\omega }_{2}}=\left( \frac{M\omega }{M+2m} \right)\]
