Question

Calculate the pressure exerted by an book of mass 20kg occupying an area of 2 m square.​

Answer 1

The answer is 100 Pa.

The formula for calculating pressure is :

Pressure = Force ÷ Area

We are given that :

• mass = 20 kg
• area = 2 m²

We also know that :

Force = mass ×g

So, force will be :

• F = 20 × 10
• F = 200 N

Now, we can finally calculate pressure :

• P = 200 ÷ 2
• P = 100 Pa
