NEET Physics Pressure in Fluids MCQ Question
A fluid with a density of 1000 kg/m³ is at rest in a container. If the pressure at a depth of 5 meters is 150,000 Pa, what is the atmospheric pressure above the fluid?
100,000 Pa
50,000 Pa
200,000 Pa
75,000 Pa
Correct Answer
Detailed Explanation
Using the pressure-depth relationship P = Pa + ρgh, where P is the total pressure at depth, Pa is atmospheric pressure, ρ is fluid density, g is acceleration due to gravity, and h is depth. Solving for Pa gives 100,000 Pa.
