Question

A hand presses down on the book in FIGURE Q6.12. Is the normal force of the table on the book larger than, smaller than, or equal to mg?

Short answer

The book's usual force is more than$mg$.

Step-by-step solution

Introduction

Surfaces exert a normal force in order to prevent solid things from passing through them. The normal force is a contact force. On two surfaces that are not in contact, a normal force cannot be applied.

Explanation

The usual force is$n=F+mg$when a strong hand bears down on it 'F'.

As a result, the book's normal force is greater than the normal force on the book$mg$.
