The law that states objects exert equal and opposite forces to each other is Newton's Third Law of Motion.

Here's a breakdown:

* Newton's Third Law of Motion: For every action, there is an equal and opposite reaction.

* Meaning: When one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.

* Example: When you push against a wall, the wall pushes back on you with an equal and opposite force.
