In the figure, the top tank, which is open to the atmosphere,contains water and the bottom tank contains oil covered by apiston. The tank on the right has a freely movable partition thatkeeps the oil and water separate. The partition is a verticaldistance 0.10 m below the open surface of the water. If the pistonin the bottom tank is 0.50 m below the open surface of the waterand has a surface area of 8.3 x 10-3 m2, what must the mass of thepiston be to keep the system in mechanical equilibrium. Forsimplicity, ignore the mass of the partition.
