NEET Physics Pascal's Law MCQ Question
A hydraulic lift is used to raise a car with a weight of 15000 N. If the area of the smaller piston is 0.05 m² and the area of the larger piston is 1.0 m², what is the minimum force required on the smaller piston to lift the car?
750 N
1500 N
3000 N
6000 N
Correct Answer
Detailed Explanation
According to Pascal's Law, pressure applied on a confined fluid is transmitted undiminished in all directions. Therefore, the force is calculated as F1/A1 = F2/A2, giving F1 = (A1/A2) * F2 where F2 is the weight of the car.
