Question

Pressure exerted on a body immersed in a liquid does NOT depend on:

• A. the depth of the body inside the liquid.
• B. the density of the liquid.
• C. the surface area of the body.
• D. the weight of the liquid column above the body.

Answer 1

The correct option is C the surface area of the body.

Liquid pressure on a body is due to the weight of the liquid column above the body. The weight of the liquid column which is pressing the body from above, depends on

• the height of the column of liquid present above that body (the depth of the body inside the liquid) ; and
• the density of that liquid.

Therefore, we can say that the pressure exerted on a body immersed in a liquid does not depend on the surface area of the body.
