A dentist’s chair makes use of Pascal’s principle to move patients up and down. Together, the chair and a patient exert a downward force of 2269 N. The chair is attached to a large piston with an area of 1221 cm2. To move the chair, a pump applies force to a small piston with an area of 88.12 cm2. What force must be exerted on the small piston to lift the chair?
