A fluid filled container is shown below. Oil fills the left side of the "U" to a depth of 26.0 cm while water fills the rest. The oil has a density of 753 kg/m3. The radius of the tube on the left side is 23.0 cm and the radius of the tube on the right side is 45.0 cm.

• If the height of the fluid in the two cylinders is exactly the same, what mass should be placed on the left cylinder to balance the system?
• What is the pressure at the bottom of the oil when the system is balanced?
• If the mass on the left is removed, what is the difference in heights between the two sides?
