NEET Physics Pressure in Fluids MCQ Question
What is the pressure sustained by the femurs when supporting a human body of mass 40 kg with a total cross-sectional area of 20 cm²?
2000 Pa
4000 Pa
2500 Pa
5000 Pa
Correct Answer
Detailed Explanation
The average pressure is calculated as P = F/A, where F is the force due to the weight of the body (400 N) and A is the total cross-sectional area (20 × 10⁻⁴ m²). This gives an average pressure of 2500 Pa.
