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

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.

The book and the table both have acceleration (due to gravity) of 9.8 m/s/s.
The book and the table both have acceleration (due to gravity) of 9.8 m/s/s.

The book and the table have the same weight.

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 explanation adheres to Newton's first law of motion, which states that an object at rest will remain at rest if the net forces acting on it are balanced. In this case, the downward force of gravity (the weight of the book) is balanced by the upward normal force exerted by the table.
