Step-by-step explanation:
According to newton's 3rd law of motion, the action and reaction force act in two different objects. For every action, there is an equal and opposite reaction.
Let F₁₂ is the force that object 1 experienced on object 2 and F₂₁ is the force that object 2 will experience on object 2. So,
F₁₂ = -F₂₁
So, an action-reaction pair of forces have equal magnitudes in the opposite direction.
