NEET Physics Pascal's Law MCQ Question
Consider a hydraulic lift as a practical application of Pascal's Law. The lift consists of a large piston supporting a car and a small piston where force is applied. If the force applied on the small piston is increased, what happens to the pressure transmitted to the large piston?
The pressure increases equally on the large piston.
The pressure decreases on the large piston.
The pressure remains unchanged on the large piston.
The pressure increases unequally on the large piston.
Correct Answer
Detailed Explanation
According to Pascal's Law, an increase in pressure on a confined fluid is transmitted undiminished to every point of the fluid and the walls of its container. Thus, increasing the force on the small piston increases the pressure equally on the large piston.
