Question

A book has a mass of 400g the surface of the book in contact

Answer 1

Answer:

The pressure exerted on the table due to the book is 200 N/m².

Explanation:

The pressure exerted on the table due to the book is 200 N/m².

The given parameters;

mass of the book, m = 400 g = 0.4 kg

dimension of the table,  = 0.10m x 0.20 m.

gravitational field strength g =  10 N/kg.

The area of the table is calculated as follows;

A = 0.1 x 0.2 = 0.02 m²

The pressure exerted on the table due to the book is calculated as follows; where;

F is the force of the book due to its weight

Thus, the pressure exerted on the table due to the book is 200 N/m².
