A cylindrical block of wood (density=650 kg m-3), of base area 30 cm2 and height 54 cm, floats in a liquid of density 900 kg m-3. The block is depressed slightly and then released. The time period of the resulting oscillations of the block would be equal to that of a simple pendulum of length (nearly) :
As we learned
Equation of S.H.M. -
Let Block is Hosting with h depth in water.
Let it is depressed by x
(for simple pendulum)
