Fig. 3.1 displays the load-extension graphs for two springs, A and B. The vertical axis gives load in N, while the horizontal axis shows extension in mm. The two straight-line plots are labelled spring A and spring B.
(a)[1]
Determine the extension of spring A under a load of 10 N.
(b)[2]
State which spring is easier to stretch and explain your answer.
(c(i))[1]
Calculate the extension of this spring for a load of 6.0 N.
(c(ii))[2]
Describe how a student could use the equipment in Fig. 3.2 to collect accurate readings for a load-extension graph for this spring.
