Apparatus Beam balance, weight box, forceps, two objects of different masses. As seen in the figure below, the points all lie on a straight line, and this is what Hooke’s law defines as the relationship between force and spring extension. In a spring balance the space between 0 and 25 g marks is divided into 10 equal parts. Balance A has a range of 0 to 250 g and a least count of 2.5 g, while balance B has a range of 0 to 1000 g and a least count of 10g. As we add more masses and increase the force applied to the Newton spring balance we have more points to plot on the graph. A spring scale or spring balance or newton meter is a type of mechanical force gauge or weighing scale.It consists of a spring fixed at one end with a hook to attach an object at the other.
