Instead of Cables, a Hydraulic Lift Raises an Elevator Weighing

Instead of cables, a hydraulic lift raises an elevator weighing 2.5 kiloNewtons. The input piston has a 2.0 cm diameter and the lift piston has a 28. cm diameter (See Figure 9-3)

What minimum force must be applied to the input piston?

A) 0.49 MN
B) 35. kN
C) 2.5 kN
D) 13. N
E) 0.18 kN
