Question

Pressure due to fixed force varies _________ to the area of the surface.

Answer 1

Explanation:

1. Fluid pressure is a measurement of the force per unit area on an object in the fluid or on the surface of a closed container.
2. Mathematically pressure can be given as,

$\mathrm{Pressure}=\frac{\mathrm{Force}}{\mathrm{Area}}=\frac{\mathrm{F}}{\mathrm{A}}$

3. So we can say that at constant force, pressure is inversely proportional to the area.

4. At a constant area, pressure is directly proportional to the force.

5. Also at constant pressure, force is directly proportional to the area.

Hence, pressure due to fixed force varies inversely proportional to the area of the surface.
