Question

A pressure of 10 Pa acts on an area of 3.0 m². What is the force acting on the area? What force will be exerted by the application of same pressure if the area is made one-third?

Answer 1

Area = 3 m²
Pressure = 10 Pa
Force = ?
$\mathrm{Pressure}=\frac{\mathrm{Force}}{\mathrm{Area}}$
Pressure × Area = Force
10 × 3 = Force
30 N = Force
Answer: Force = 30 N.
If the area is made one-third, then
Area = 3 m² (1/3 of 3 m²) = 1 m²
Pressure = 10 Pa
Force = ?

$\mathrm{Pressure}=\frac{\mathrm{Force}}{\mathrm{Area}}$
Pressure × Area = Force
10 × 1 = Force
10 N = Force
Answer: Force =10 N.
