NEET Physics Pascal's Law MCQ Question
A hydraulic lift uses a fluid with negligible viscosity to lift a car. If the small piston has a radius of 0.1 m and the large piston has a radius of 0.5 m, what is the ratio of the force applied on the small piston to the force exerted by the large piston according to Pascal's Law?
1:25
1:10
1:5
1:1
Correct Answer
Detailed Explanation
According to Pascal's Law, pressure is transmitted equally in a fluid. The force exerted by a hydraulic lift is proportional to the area of the piston. The area ratio between the small and large pistons is (π(0.5)^2)/(π(0.1)^2) = 25, giving a force ratio of 1:25.
