A cubic block of side a is connected with two similar vertical springs as shown. Initially, bottom surface of the block of density `sigma` touches the surface of the fluid of density `2sigma` while floating. A weight is placed on the block so that it is immersed half in the fluid, find the weight.

A cubical block of wood of edge a and density rho floats in water of density 2rho . The lower surface of the cube just touches the free end of a mass less spring of force constant K fixed at the bottom of the vessel. The weight W put over the block so that it is completely immersed in water without wetting the weight is

A drop of liquid of density rho is floating half-immersed in a liquid of density d . If sigma is the surface tension the diameter of the drop of the liquid is

A wooden block of mass 120 kg floats on water. The density of the wooden block is 600kg*m^(-3) . The weight that should be placed on the wooden block so that it just sinks will be

A spring is connected between two blocks as shown in the diagram. Initially the blocks are held stationary and suddenly they are released. Find the ratio of maximum kinetic energy with spring compressed the block of mass m to that of mass 2m.
