A small can of radius r=7.0cm and height h=10.0cm is suspended by a string in a beaker of water so that it's depth is 15cm below the surface. the can is heavy enough that it would sink if it were not tied to the string.(the density of water is 1g/cm^3)
A) What is the force that the water exerts on top of the can?
B) What is the force that the water exerts on the bottom of the can?
C) If the can has a mass of 2000 grams, what is the tension in the string?
