A 5.0kg cube of metal has a density of 3000 kg m3 and is held by a vertical string while immersed in water which has a density of 1000 kg m3 . Assume that the cube is oriented so that all the faces are either vertical or horizontal. a) What is the length of each side of the cube? (b) What is the difference in pressure between the top of the cube and the bottom? (c) What are the vertical components of force due to water pressure on the top and bottom of the cube? (d) Assuming that the cube is in equilibrium, what is the tension in the string?

A 10cmx10cmx10cm cube of density 650 kg/m3 and is submerged in a container filled with water of density 1000 kg/m3. It is initially held at rest by a string which is attached to the bottom of the container, as shown in the figure. When we cut the string, the cube starts moving upwards. Find the initial acceleration of the cube, immediately after it is released. Answer in units of m/s2.
