The wrong option about gravitational force among the following is:a) g...
The correct answer is d
An action-reaction pair of forces are always equal and opposite, but two forces that are equal in magnitude and opposite in direction are NOT always an action-reaction pair! On the other hand, the reaction force to the normal force pushing up on the book is the force of the book pushing down on the table.

Gravitational Force
The gravitational force is the force of attraction that exists between any two objects with mass. It is one of the fundamental forces in nature and is responsible for holding celestial bodies like planets, moons, and stars in their respective orbits. Here, we will discuss the incorrect option about gravitational force.
Incorrect Option: d) Gravitational force does not form an action-reaction pair
The action-reaction principle, also known as Newton's third law of motion, 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 an equal and opposite force on the first object.
In the case of gravitational force, it forms an action-reaction pair. Let's consider two objects, A and B, with masses mA and mB, respectively. The gravitational force exerted by object A on object B is equal in magnitude and opposite in direction to the gravitational force exerted by object B on object A. This principle holds true for any two objects in the universe.
Example
To understand this concept better, let's take the example of the Earth and a person standing on its surface. The Earth exerts a gravitational force on the person, pulling them towards its center. According to Newton's third law, the person also exerts an equal and opposite gravitational force on the Earth. However, due to the enormous mass of the Earth, the effect of the person's gravitational force on the Earth is negligible.
Conclusion
In conclusion, the incorrect option about gravitational force is d) "Gravitational force does not form an action-reaction pair." The gravitational force does indeed form an action-reaction pair, as stated by Newton's third law of motion. It is important to understand this fundamental principle when studying the interactions between objects in the universe.
