Question

A book of mass $20g$ is placed on a table. Find the thrust exerted by the book on the table. (Take acceleration due to gravity as $10m{s}^{-2}$)

Answer 1

Given,

Mass of the book, $m=20g=0.02kg$

Acceleration due to gravity, $a=g=10m/s^2$

Thrust is the force acting in a particular direction.

Thrust, $F=m\times a$

$F=0.02\times 10$

$F=0.2N$
