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 of spring constant k,such that it is half submerged in a liquid of density sigma at equilibrium position. What is the extension of the spring when it is in equilibrium?

1.	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 of spring constant k,such that it is half submerged in a liquid of density sigma at equilibrium position. What is the extension of the spring when it is in equilibrium?
Answer» ANSWER :`[(MG)/L(1-(LAsigma)/(M))]`
