A) \[\frac{{{\omega }^{2}}{{l}^{2}}}{2g}\]
B) \[\frac{{{\omega }^{2}}{{l}^{2}}}{3g}\]
C) \[\frac{{{\omega }^{2}}{{l}^{2}}}{g}\]
D) \[\frac{{{\omega }^{2}}{{l}^{2}}}{6g}\]
Correct Answer: D
Solution :
Applying energy conservation, we get \[mgh=\frac{I{{\omega }^{2}}}{2}=\frac{m{{l}^{2}}}{3}\times \frac{{{\omega }^{2}}}{2}\Rightarrow \frac{{{\omega }^{2}}{{l}^{2}}}{6g}\]You need to login to perform this action.
