Angle between Action and Reaction
The angle between the action of the book on the table and the reaction of the table on the book is determined by the normal force and weight of the book.
Explanation
When a book is placed on a table, it exerts a force on the table, known as the action force. The table, in turn, exerts an equal and opposite force on the book, known as the reaction force. This is known as Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
The normal force is the force that the table exerts on the book, perpendicular to the surface of the table. The weight of the book is the force exerted by the Earth on the book, directed towards the center of the Earth.
The angle between the action of the book on the table and the reaction of the table on the book is zero degrees, as the forces are acting in opposite directions and are perpendicular to each other. Therefore, option 'A' is the correct answer.
Conclusion
The angle between the action of the book on the table and the reaction of the table on the book is determined by the normal force and weight of the book. In this case, the angle is zero degrees, as the forces are acting in opposite directions and are perpendicular to each other.
