A rod of mass m and length L is pivoted ...

A rod of mass `m` and length `L` is pivoted at a point `O` and kept in horizontal position as shown in figure. Now it is released from this position so that it can rotates freely about the point `O` in downward direction. When it becomes vertical

Angular velocity of rod will be `sqrt((6g)/(L))`

Angular velocity of rod will be `sqrt((3g)/(L))`

The velocity of point `P` will be `sqrt(3gL)`

The velocity of point `P` will be `sqrt(6gL)`
