The correct answer is option 'C': Both the stone and the earth attract each other.
Explanation:
The force of attraction between two objects depends on their masses and the distance between them. This force is known as gravitational force. According to Newton's law of universal gravitation, every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
When a stone falls towards the Earth, it is attracted by the Earth due to the gravitational force. At the same time, the stone also exerts a gravitational force on the Earth. These forces are equal in magnitude but opposite in direction, as stated by Newton's third law of motion.
- Both the stone and the Earth attract each other:
The stone attracts the Earth with the same force as the Earth attracts the stone. This is because the force of gravity is mutual and acts in both directions. The stone falls towards the Earth because the Earth has a much larger mass than the stone, resulting in a larger force of attraction.
- Attraction of the stone by the Earth:
The Earth's mass is much greater than the stone's mass, so the stone experiences a greater force of attraction towards the Earth. This force causes the stone to accelerate towards the Earth and fall.
- Attraction of the Earth by the stone:
Similarly, the stone's mass is much smaller compared to the Earth's mass. However, the Earth also experiences a force of attraction towards the stone. But due to the Earth's large mass, this force is negligible and the Earth's motion can be considered negligible.
Therefore, both the stone and the Earth attract each other with a force of gravity. The stone falls towards the Earth due to the larger force of attraction exerted by the Earth.

Explanation:
When a stone falls towards the earth, both the stone and the earth attract each other due to the force of gravity. This is known as the law of universal gravitation. Here's a detailed explanation:
Law of Universal Gravitation:
- The law of universal gravitation states that every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
- This means that both the stone and the earth exert a gravitational force on each other.
Stone's attraction towards Earth:
- The stone is attracted towards the earth due to its gravitational force.
- The earth has a much larger mass than the stone, so the force of attraction is more significant on the stone.
- This force causes the stone to accelerate towards the earth, resulting in its fall.
Earth's attraction towards Stone:
- According to Newton's third law of motion, for every action, there is an equal and opposite reaction.
- As the stone attracts the earth towards itself, the earth also attracts the stone towards it with an equal force.
- However, due to the earth's large mass, the acceleration caused by this force is negligible and is not noticeable.
Conclusion:
- Both the stone and the earth attract each other due to the force of gravity.
- The stone falls towards the earth as a result of this attraction.
- Therefore, option (C) is correct: Both the stone and the earth attract each other.
