In a Hydraulic Garage Lift, the Small Piston Has a Radius

Multiple Choice

In a hydraulic garage lift, the small piston has a radius of 5.0 cm and the large piston has a radius of 15 cm. What force must be applied on the small piston in order to lift a car weighing 20,000 N on the large piston? Assume the pistons each have negligible weight.

A) $2.9 \times 10 ^ { 3 } \mathrm {~N}$
B) $2.2 \times 10 ^ { 3 } \mathrm {~N}$
C) $5.0 \times 10 ^ { 3 } \mathrm {~N}$
D) $6.7 \times 10 ^ { 3 } \mathrm {~N}$
