Hang a 100g mass at a distance S = 2.5cm from the end of the rule and balance the arrangement to restore equilibrium. Measure the distance X between the knife edge and P (point of attachment of mass) the 231²8/02 GTF = 50.9 Table 9.1 St X± 2.5 Repeat the experiment for S = 5, 10, 20, 30, 40cm.

Plot a graph of S against X. 3. What is the slope? 4. From the graph find the value of S for which X = 0, 5. Deduce the value of m from the graph. 30.0 40.0 12-6 6.5 JULY 14, 2022 (100+m)X m + L 100 mg Amos Vamcy JD- 95061 Sectin 7 scale para plane (as in Figure 8.1). idte your results. at Mw just begins to slide.
