A student investigates the forces supporting a metre ruler to determine the weight of the metre ruler. He uses the apparatus shown in Fig. 1.1. The scale of the metre ruler faces upwards. Fig. 1.1 The student adjusts distance $$\(d\)$$ between the 0.0 cm mark and the 1.50 N load, as shown in Fig. 1.1. He moves the thread supporting the 1.50 N load so that it is at the mark on the metre ruler shown in Fig. 1.2. The metre ruler is not drawn to scale. Record the distance $$\(d\)$$ indicated on Fig. 1.2. d = .....................................................cm (ii) The reading on force meter X is shown in Fig. 1.3. Fig. 1.3 Record $$\(F_{X}\)$$, the reading on force meter $$\(X\)$$ shown in Fig. 1.3. $$\[ F_{X}= \]$$ .................................................. N
