Aball strikes a wall. it exerts a force of 10 n to the left against the wall and bounces off. what force does the wall exert on the ball? 10 n to the left 10 n to the right more than 10 n to the left more than 10 n to the right

Before going to solve this question first we have to understand Newton's third law of motion.

As per Newton's third law of motion for every action there is an equal and opposite reaction.In a simply way we can say that whenever we exert a force on a body,same amount of force is applied on us by the body.The force exerted by a body is called its action and the force it gets in return is called reaction. Action and reaction always act on two different bodies and their direction will be opposite to each other.

As per the question the ball exerts a force of 10 N on the wall.Its the force of action.

we have been asked to calculate the force exerted by the wall on the ball i.e reaction.

From Newton's third of motion ,it's obvious that  the magnitude of force must be 10 N.

The direction of force is to the left.Hence the direction of reaction must  be towards right.

Hence the answer of this question is 10 N to right.
