The book’s weight and the upward force the table exerts on the book have equal magnitude but opposing directions.

The book and the table have the same weight.
The book and the table have the same weight.

Gravity is a net force acting on the book in a downward direction.
Gravity is a net force acting on the book in a downward direction.

Answer 1

The correct response is:

The book’s weight and the upward force the table exerts on the book have equal magnitude but opposing directions.

This statement describes the condition for equilibrium, where the forces acting on the book are balanced. The weight of the book (downward force due to gravity) is equal in magnitude to the normal force exerted by the table (upward force), resulting in a net force of zero and thus a state of equilibrium.
