A 5.0 kg 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. 1. What is the difference in pressure between the top of the cube and the bottom? 2. What are the vertical components of force due to water pressure on the top and bottom of the cube? 3. Assuming that the cube is in equilibrium, what is the tension in the string? p=p°-pgz I was wondering how you get the pressure when you are only given density. Also, you do not know how deep the metal is... does that not matter? Thanks in advance! Any hints would be helpful.
