Question

Two syringines of different cross sections filled with water are connected with a tightly fitted rubber tube filled with water.diameters of smaller piston and larger piston are 1cm and 3cm.find the force exerted on larger piston when a force 10N is applied to a smaller piston

Answer 1

F1(force on smaller piston)

F2(force on larger piston)

A1(area of smaller piston)

A2(area of larger piston)

F2=A2/A1*F1

   =pai{3/2*10(power -2)m}(power 2)/pai{1/2*10(power-2)m}(power2)*10N

                     =90N
