A block of wood is floating in water. The volume of the block is .01m^3. A force is pushing on the top of the block so that the top surface of the block is just at the level of the water. What is the magnitude of the force? The density of the wood is .5 * 10^3 kg/m^3 and the density of water is 1 * 10^3 kg/m^3.
