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 (rho) at equilibrium position. When the cylinder is given a small downward push and released it starts oscillating vertically with small amplitude. If the force constant of the spring is (k), the prequency of oscillation of the cylindcer is.

A uniform cylinder of mass m, length l and cross sectional area A is suspended with its vertical from a fixed point, with the help of a massless spirng of force constant (K), The cylinder is then submerged in a liquid of density p. At equilibrium the cylinder remains submerged in the liquid with 1//4^(th) of its volume outside the liquid, as shown in the figure. The elongation of hte spring at this point is x_(0) . WHen the cylinder is given a slight downward push into the liquid and then released, its starts oscillating with vertical S.H.M. of small amplitude. The elongation X_(0) produced in the springs when the syste is in equilibrium is

A uniform cylinder of height h, mass m and cross sectional area A is suspended vertically from a fixed point by a massless spring of force constant k, A beaker full of water is placed under the cylinder so that 1//4^(th) of its volume is submerged in the water at equilibrium position. When the cylinder is given a small downward push and released, it starts oscillating vertically with small amplitude. Calculate the frequency of oscillation of the cylinder, Take, density of water = rho .
