Question

Which of the following are factors affecting the pressure at a point in a liquid?

• A. Acceleration due to gravity
• B. Density of the liquid
• C. Depth of the point below the free surface
• D. All of the above

Answer 1

The correct option is D

All of the above

The pressure at a point inside the liquid depends directly on the acceleration due to gravity (g), density of the liquid (ρ) and depth of the point below the free surface (h). Now, since there is atmospheric pressure above the free surface of the liquid, so the total pressure at a depth inside a liquid is defined by the atmospheric pressure and pressure due to the liquid column, i.e., P = $P_0+h\rho g$.
