AIEEE 2009 | Rotational Motion Question 243 | Physics

A thin uniform rod of length $$l$$ and mass $$m$$ is swinging freely about a horizontal axis passing through its end. Its maximum angular speed is $$\omega $$. Its center of mass rises to a maximum height of:

$${1 \over 6}\,\,{{l\omega } \over g}$$

$${1 \over 2}\,\,{{{l^2}{\omega ^2}} \over g}$$

$${1 \over 6}\,\,{{{l^2}{\omega ^2}} \over g}$$

$${1 \over 3}\,\,{{{l^2}{\omega ^2}} \over g}$$
