A book is resting on a table in a state of equilibrium. Which statement is true about the forces acting on the book?

options:

The book experiences balanced forces because the force of gravity pushing down on the book is greater.
The book experiences balanced forces because the force of gravity pushing down on the book is greater.

The book experiences unbalanced forces because the force of gravity pulling down on the book and the force of the table pushing up are equal.
The book experiences unbalanced forces because the force of gravity pulling down on the book and the force of the table pushing up are equal.

The book experiences unbalanced forces from friction, gravity and the table.
The book experiences unbalanced forces from friction, gravity and the table.

The force of gravity pulling down the book and the force of the table pushing up on the book are equal.

1 answer

In a state of equilibrium, the forces acting on the book are balanced. Specifically, the force of gravity acting downwards on the book is equal to the normal force exerted by the table acting upwards on the book. Therefore, the correct statement is:

The force of gravity pulling down the book and the force of the table pushing up on the book are equal.

So, the last option provided is true.
