When both spring balances show the same reading, it indicates that the force exerted by one balance on the other is equal in magnitude but opposite in direction. This phenomenon illustrates the balance of action and reaction forces according to Newton’s third law of motion.

When both spring balances show the same reading while a force is applied, it indicates that the force applied is being equally distributed between the two objects. According to Newton’s Third Law of Motion, for every action, there is an equal and opposite reaction. In this case, the force applied is causing an equal and opposite force in the connected objects (spring balances). The matching readings imply that the tension or force is transmitted seamlessly through the system, highlighting the balanced interaction between the objects. This consistent reading affirms the law of action and reaction, demonstrating the equilibrium of forces in the system.
