An experiment was conducted at a certain Secondary School to study the relationship between force applied and the extension of a spiral spring. The results were as follows: Note: Initial reading (lo) = 53.4cm Weight, W (g) | Force (N) | Length, l (cm) | Extension, e = (l – lo) cm -----------------|-----------|----------------|------------------------ 50 | 0.5 | 55.4 | 100 | 1.0 | 58.0 | 150 | 1.5 | 60.4 | 200 | 2.0 | 62.8 | 250 | 2.5 | 65.2 | 300 | 3.0 | 67.5 | i. Complete the table above. ii. Plot the graph of the force against extension (on the graph paper). iii. From the graph find the slope.
