According to Newton's third law, the forces of action and reaction are equal in magnitude and opposite in direction. Therefore, the force exerted by Earth on the Sun is equal in magnitude to the force exerted by the Sun on Earth. F₁ and F₂ are two different ways of expressing the same magnitude, so they must be equal.

Let F1 Be the Magnitude of the Gravitational Force Exerted

Let F₁ Be the Magnitude of the Gravitational Force Exerted
