The book is in a state of equilibrium because the forces acting on it are balanced.
The weight of the book is a downward force due to gravity. At the same time, the table exerts an equal and opposite upward force on the book, known as the normal force. These two forces have equal magnitudes but act in opposite directions, resulting in a net force of zero. Therefore, the book remains stationary on the table.
Additionally, since the book and the table have the same weight, they experience the same gravitational force. This means that the force exerted by the table is enough to counteract the weight of the book, resulting in equilibrium.
Why is a book resting on a table in a state of equilibrium?
The book and the table both have acceleration (due to gravity) of 9.8 m/s/s.
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
The book and the table have the same weight.
