Calculate the pressure exerted by an book of mass 20kg occupying an area of 2 m square.​
kotykmax [81]

The answer is 100 Pa.

The formula for calculating pressure is :

<u>Pressure = Force ÷ Area</u>

<u />

We are given that :

  • mass = 20 kg
  • area = 2 m²

We also know that :

<u>Force = mass ×g</u>

<u />

So, force will be :

  • F = 20 × 10
  • F = 200 N

Now, we can finally calculate pressure :

  • P = 200 ÷ 2
  • P = 100 Pa
