Question

The force exerted by a body on Earth is ____________ a force exerted by the Earth on the body.

Answer 1

Newton's third law of motion:

• According to Newton's third law of motion, to every action there is an equal and opposite reaction.
• Here, a force exerted by a body on Earth is the action and the force exerted by the Earth on the body is the reaction.

Hence the force exerted by a body on Earth is equal and opposite a force exerted by the Earth on the body.
