360994 A sphere of solid material of specific gravity 8 has a concentric spherical cavity and just sinks in water. Then the ratio of radius of cavity to that of outer radius of the sphere must be:

360995 The total weight of a piece of wood is \(6\;kg\). In the floating state in water its \(\dfrac{1}{3}\) part remains inside the water. On this floating piece of wood what maximum weight is to be put such that the whole of the piece of wood is to be drowned in the water?

360996 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 \(\sigma\) at equilibrium position. The extension \(x_{0}\) of the spring when it is in equilibrium is:
