Answer:
5N
Explanation:
From Newton's third law, we understood that to every action, there is an equal an opposite reaction.
Since Arti's foot exerts a force of 5N on the ball, then, an equal and opposite force of 5N will be exerted on Arti's foot as understood from Newton's third law.
Therefore, a force of 5N will be exerted on Arti's foot.
