Question

One piston in a hydraulic lift has an area that is twice the area of the other. When the pressure at the smaller piston is increased by Ap the pressure at the larger piston: Select one a, increases by Ap/2 b. Increases by 4p c. does not change d. increases by Ap

Answer 1

(1) Pressure is always the same in both pistons, if pressure at small piston is increased by $\Delta P$ then pressure at larger piston will also incresed by $\Delta P$ .

option (d) is correct.
