Answer:
m = 1.53 kg
Explanation:
Given that,
The sides of a book are 30cm by 25cm.
Pressure exerted, P = 200 Pa
We need to find the mass of the block. We know that,
Pressure = Force/area
So,
[tex]P=\dfrac{mg}{A}\\\\m=\dfrac{PA}{g}[/tex]
Put all the values,
[tex]m=\dfrac{200\times 0.3\times 0.25}{9.8}\\\\m=1.53\ kg[/tex]
So, the mass of the block is 1.53 kg.
