NEET Physics Pressure in Fluids MCQ Question with Solution

What is the force exerted by a fluid with density $\rho = 1000 \, \text{kg/m}^3$ on a window of area $0.04 \, \text{m}^2$ submerged 10 meters below the surface?

A

3920 N

B

9800 N

C

1960 N

D

7840 N

Correct Answer

Option D

Detailed Explanation

Using the formula for gauge pressure $P_g = \rho g h$ and force $F = P_g A$ , with $\rho = 1000 \, \text{kg/m}^3$ , $g = 9.8 \, \text{m/s}^2$ , $h = 10 \, \text{m}$ , and $A = 0.04 \, \text{m}^2$ , the force is $F = 1000 \times 9.8 \times 10 \times 0.04 = 7840 \, \text{N}$ .
