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.
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.
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. Alternatively, the book’s weight and the upward force the table exerts on the book have equal magnitude but opposing directions. Both of these responses explain why the book is in a state of equilibrium when resting on a table.
is that true
Yes, that is true. When a book is resting on a table, it is in a state of equilibrium because the book's weight, which is a force acting downwards, is balanced by the upward force exerted by the table. These two forces have equal magnitudes but opposite directions, resulting in a balanced or stable condition.
