Q .
The Hydraulic press used to lift a car is based on the following principle
A)
Pascal's Principle
B)
Magnus Effect
C)
Bernoulli's Principle
D)
Archimedes Principle

Correct Answer :   Pascal's Principle

However, because A₁ has 10 times the area of A₁, it will produce a force (F₂) that is 10 times greater than the original force (F₁). Through Pascal's principle, a relatively small force exerted on a hydraulic press can be magnified to the point where it will lift a car.
