State Newton's third law. Give an example and explain how the example comes under this law.

For example, if the Earth is pulling down on you with a gravitational force of 500 N, you are also pulling up on the Earth with a gravitational force of 500 N. ... Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
Newton's Third Law of motion states that every action force has an equal and opposite reaction force. If a body A exerts a force on B, then body B will exert an equal magnitude of force on A but in the opposite direction.
Example:
When a man is pushing a wall, he is liable to fall back. This is because when he is pushing the wall, the wall is exerting an equal and opposite reaction force, so the man falls back. However, the wall doesn't move because it has a lot of mass so it resists motion.
