NEET Physics Pascal's Law MCQ Question
A hydraulic lift is designed using Pascal's Law. If a force of 200 N is applied to a small piston with an area of 0.01 m², what will be the force exerted by a large piston with an area of 0.1 m²?
2000 N
200 N
20 N
400 N
Correct Answer
Detailed Explanation
Using Pascal's Law, the pressure applied on the small piston is transmitted undiminished to the large piston. Thus, the force exerted by the large piston is F = (A2/A1) * F1 = (0.1 m²/0.01 m²) * 200 N = 2000 N.
