Question

Calculate the pressure produced when a force of 50N is applied over an area of 20 cm squar.

Answer 1

Given force is 50N and Area is 20 cm^2
Convert area cm into metre
20/100=0.02
Pressure=Force/ Area
=50/0.2
=250Pa

Answer 2

The pressure produced when a force of 50N is applied over an area of 20 cm², is 2.5 × 10⁴ Pa.

Given,

Force = 50 N,

Area = 20 cm².

To find,

Pressure.

Solution,

Pressure is defined as the force that is exerted in a direction normal or perpendicular to the surface of a body or any object distributed over a unit area. Mathematically, it is expressed as

$P=\frac{F}{A} \hfill (1)$

where F is the force acting perpendicular to area A.

Here, it is given that,

F = 50 N,

A = 20 cm² = 20 × 10⁻⁴ m².

Thus, using (1), pressure will be

$P=\frac{50}{20 \times 10^{-4}}$

$\implies P=2.5 \times 10^{4}$ Pa

Therefore, the pressure produced when a force of 50N is applied over an area of 20 cm², is 2.5 × 10⁴ Pa.
