HOW CAN TABLE APPLY FORCE ON THE BOOK, WHY CANT'T WE SEE AND FEEL IT?

Newton's third law states that:
For every action, there is an equal and opposite reaction.
That is, in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object.
In case of a book on table, the two objects are interacting with each other. The table applies a force on book, and the book applies a force on the table. the force on book by table in upward direction balances the force exerted on it by gravity. Thus, there is no net force on the book and it stays on the table. that's why you can not see any force on the book.
