The reading of the spring balance should be taken without any parallax error. He showed that when a spring is fixed at one end and a force is applied to the other, the extension of the spring is proportional to the applied force, provided the force is not large enough to stretch the spring permanently. To study the Third Law of Motion using two spring balances. At the end of the spring (where the hook is), a mass of 100 grams was placed and as a result the spring started to extend downwards. Poke one small hole in the bottom of each cup to provide drainage. Record the readings carefully of both spring balance and measuring cylinder by keeping the level of eye and the mark of reading same/parallel. If weights are not available, it is possib The Newton spring balance uses a law known as Hooke’s Law to relate the spring extension to the force being measured.
