Respuesta :
Option A is the correct representation of Newton's third law of motion.
Option A: A gun moves backward while firing a bullet.
Newton's Third Law of Motion
The third law of motion can be defined as when two objects, interact with each other, they apply force on each other. The force applied by the objects will be equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction which defines that forces always comes in pair.
Option A is given that a gun moves backward while firing a bullet. This represents Newton's third law of motion. When the bullet is fired in the forward direction, it applies force to the gun. The force is equal in magnitude as compared to the force applied on the bullet by the gun. The direction will be opposite as the bullet moved forward while the gun moves backward.
Hence we can conclude that Option A is the correct representation of Newton's third law of motion.
