A hydraulic press consists of two vertical cylinders of circular cross-sectional areas 6cm2 and 120cm2 that are joined at the base. The press contains oil of relative density 0.93, and the friction between the pistons and the cylinder walls is negligible. Initially the pistons are at the same level

a) Calculate the upward force on the larger piston due to a downward force of 30N on the smaller one.

b) Through what distance does the larger piston rise?

c) What is now the upward force on the larger piston due to a downward force of 30N on the smaller one?
