Two syringes of different cross-sections...

Two syringes of different cross-sections (without needles) filled with water are connected with a tightly fitted rubber tube filled with water. Diameters of the smaller piston and larger piston are 1.0cm and 3.0 cm respectively.
(a) Find the force on the larger piston when a force of 10N is applied to the smaller piston.
(b) The smaller piston is paused in through 6.0 cm, much does the larger piston move out?
