Question

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 σ at equilibrium position. The extension x 0 of the spring when it is in equilibrium is :, Mg k 1 - LA σ 2 M, Mg k 1 + LA σ M, Mg k, Mg k 1 - LA σ M

MARKS App · Accepted Answer

kx 0 + F B = mg kx 0 + σ L 2 Ag = Mg x 0 = Mg - σ LAg 2 k = Mg k 1 - σ LA 2 M
