NEET Physics Pressure in Fluids MCQ Question
In the diagram shown above, if the pressure at point 1 is P1 and at point 2 is P2, which of the following expressions correctly represents the relationship between P1 and P2 given the height h between them?
P2 = P1 + ρgh
P1 = P2 + ρgh
P1 = P2 - ρgh
P2 = P1 - ρgh
Correct Answer
Detailed Explanation
According to the variation of pressure with depth, the pressure increases with depth in a fluid. Therefore, P2 must be greater than P1 by an amount equal to ρgh, where ρ is the fluid density and h is the height difference.
