Question

In a car lift, compressed air exerts a force on a piston of area of 5.00 m ^2 .This pressure is transmitted to a second piston of area of 15.0 m^2.How large a force must the compressed air exert to lift a 1.33 × 10^4 N car?

1- 1.48 × 10 ^3 N

2- 1.48 × 10^-3 N

3- 4.433 × 10^3 N

4- 4.433 × 10^-3 N

5- none of these

Answer 1

Answer:

According to Pascal's law, a pressure exerted on a piston creates an equal rise in pressure on another piston in a hydraulic system. Hence, the correct answer is in option (B)⇒1.47×103N.
