The areas of the pistons are 20 cm^2 and 100 cm^2. A force of 10 N is applied to the small piston. How much force is on the large pistons?

50N

Explanation:

A1 (area of the smaller piston) = 20cm² = 0.2m²

F1 (force acting on the smaller piston) = 10N

F2 (force acting on the larger piston) = ?

A2 (area of the larger piston) = 100cm² = 1m²

F1 / A1 = F2 / A2

F2 = (F1*A2) / A1

F2 = (10*1) / 0.2

F2 = 50N
