Question

A book rest on a table which it's face having a sides 30cm by 25cm . if it exerts apressure of 200pa then determine the mass of the block.​

Answer 1

m = 1.53 kg

Step-by-step 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,

`P=(mg)/(A)\\\\m=(PA)/(g)`

Put all the values,

`m=(200* 0.3* 0.25)/(9.8)\\\\m=1.53\ kg`

So, the mass of the block is 1.53 kg.
