Question

Choose the correct statement among the following :

• A. The pressure at a point in a fluid is directly proportional to the depth of the point from the surface.
• B. The pressure at a point is independent of acceleration due to gravity.
• C. The pressure at a point is directly proportional to the area of cross section.
• D. The pressure at a point is proportional to the density of the fluid.

Answer 1

Answer: (A), (D)

The correct options are
A The pressure at a point in a fluid is directly proportional to the depth of the point from the surface.
D The pressure at a point is proportional to the density of the fluid.

pressure at a point in a fluid = $\rho gh$ where $\rho$ is the density of the fluid and h is the depth of the point from the surface.

so option (A) and option (D) are correct .
