A uniform rod of length l is suspended by an end and is made to undergo small oscillations. Find the length of the simple pendulum having the time period equal to that of the rod.
2l/3
we know time period of physical pendulum
Let r be the distance between center of mass and point of suspension
Here
-----→(1)
Now, we know time period of simple pendulum
-----→(2)
L is length of simple pendulum
From (1) &(2)
