A uniform rod of length L & mass m is suspended through an end. It is shifted through an angle of π/2 radian i.e. made horizontal and then released. Find angular velocity when rod is vertical.[/B]
The Attempt at a Solution
My attempt to a problem is attached
with this post.
By energy conservation law
1/2 I ω2= mg L/2
(ω = angular velocity)
Which one is correct? N why other is wrong?[/B]
