Angle between the action of the book on the table and reaction of table on the book
When a book is lying on the table, there are two forces acting on it - the weight of the book (downward) and the normal force exerted by the table (upward). According to Newton's third law of motion, these two forces are an action-reaction pair, meaning they are equal in magnitude and opposite in direction.
Understanding Newton's third law of motion
Newton's third law states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts a force of equal magnitude but in the opposite direction on the first object.
In this case, the book exerts a downward force on the table due to its weight. Simultaneously, the table exerts an equal and opposite force on the book, known as the normal force. The normal force is the force exerted by a surface to support the weight of an object resting on it.
Angle between the action and reaction forces
The angle between the action of the book on the table (weight) and the reaction of the table on the book (normal force) is 180 degrees. This is because the weight force is acting vertically downwards, while the normal force is acting vertically upwards.
Since the two forces are opposite in direction, they form a straight line, resulting in an angle of 180 degrees between them. This angle can be visualized by drawing a straight line from the weight force to the normal force, passing through the center of the book.
Conclusion
The correct answer is option C, 180 degrees. The angle between the action of the book on the table (weight) and the reaction of the table on the book (normal force) is 180 degrees, as per Newton's third law of motion.
