A thin rod of length and area of cross section is pivoted at its lowest point P inside a stationary , homogeneous , non viscous liquid as shown in the figure.
The rod is free to rotate in a vertical plane about a horizontal axis passing through . The density of the material of the rod is smaller than the density of liquid . The rod is displaced by a small angle from its equilibrium position and then released.
If the body performs Simple harmonic motion, calculate t's angular fequency
