Answer
both A and R are true and R is the correct explanation of A
Explanation
Assertion (A) is true because hydraulic jacks are commonly used in oil extraction processes to apply large pressure over a small area to squeeze oil from seeds.
Reason (R) is true because Pascal's principle states that :
“When pressure is applied to a confined fluid, it is transmitted equally in all directions throughout the fluid.”
This principle allows a small force applied on a small piston to produce a large force on a larger piston, making the jack effective for pressing operations like oil extraction, since the hydraulic jack works because of Pascal’s principle, the Reason correctly explains the Assertion.

A hydraulic jack is used in a car workshop to lift a car. The jack consists of two connected pistons A(area = 5 cm2) and B(area = 250 cm2), filled completely with an incompressible hydraulic fluid (such as hydraulic oil). The fluid transmits pressure uniformly throughout the system. A force of 120 N is applied vertically downward on piston A.
Assuming the system to be ideal, answer the following questions:
(a) Calculate the pressure produced in the liquid by piston A.
(b) Determine the force exerted on piston B. Name the law used.
(c) Does this hydraulic jack provide a gain in force or a gain in distance? Justify your answer.
(d) If piston B rises by a height of 2 cm, calculate the distance moved by piston A.
(e) What would happen if a small air bubble enters the liquid of the hydraulic jack?
