Question

Calculate the pressure if a force of 8 n is applied over an area of 2 m2.

Answer 1

p=f÷a so, 8N÷2m²=4n per meter square

Answer 2

Given:

A force of 8 n is applied over an area of 2 m2.

To Find:

The pressures.

Solution:

To find the pressure we will follow the following steps:

As we know,

Pressure is defined as force applied per unit area and the unit of force is the newton.

The unit of the area is metre squares so the unit of pressure is newton per metre squares or Nm-2.

The formula of pressure =

$\frac{force}{area} = \frac{8}{2} = 4 \: Nm-2$

Henceforth, the pressure is 4 Nm-2.
