JEE Main2013PhysicsOscillationsActual
A uniform cylinder of length L and mass M having cross-sectional area A is suspended, with its length vertical, from a fixed point by a massless spring, such that it is half submerged in a liquid of density at equilibrium position. When the cylinder is given a downward push and released, it starts oscillating vertically with a small amplitude. The time period T of the oscillations of the cylinder will be :
Options
- ASmaller than 2 [ M (k+A g) ]^ 1 / 2
- B2 M k
- CLarger than 2 [ M (k+A g) ]^ 1 / 2
