The figure shows a schematic layout of hydraulic jack. The load to be raised weighs 20,000N. The area of cross section of the two pistons are `A_(1)=50cm^(2)` and `A_(2)=10cm^(2)`. The force (F) is applied at theend of a ligh lever bar as shown in the figure. Lenghts a and b are 4cm and 36cm respectively. Find the force (F) required to raise the load slowly.
