Explanation:
Detailed explanation-1: -The answer is also gravity! When the earth pulls you down due to its mass, then you also pull the earth up due to your mass. These two attractive gravitational forces are equal. And they are each other’s action/reaction pair from Newton’s 3rd law.
Detailed explanation-2: -(i) Action (or reaction): Earth pulls down on ball (weight) Reaction (or action): Ball pulls up on Earth.
Detailed explanation-3: -The gravitational force from the Earth pulls down and the ground pushes up on the person. The “equal and opposite” forces in this example are the two gravitational forces. The person pulls on the Earth with the same force the Earth pulls on the person.
