Answer 1

If a force is applied to the weighing end of a spring balance, and no force is applied to the other end, the spring balance will accelerate in the direction of the applied force. To measure a force on a spring balance, an equal and opposite force must always be applied to the other end. If the spring balance is hung from a fixed point, the necessary force is transmitted through the spring balance.
