According to Newton's third law of motion, the magnitude of the force that the ball exerts on the bat is equal to the magnitude of the force that the bat exerts on the ball. Therefore, the magnitude of the force that the ball exerts on the bat is also 50 newtons, which corresponds to option c.
According to Newton's third law of motion, every action has an equal and opposite reaction. This means that the magnitude of the force that the ball exerts on the bat is also 50 newtons, the same as the force exerted by the bat on the ball. So, the correct answer is option (c) 50 N.
