CAPE Physics Unit 1 · 2016 · Paper 2 · Question 3(b)(i)

A spring manufacturer tests the properties of a spring by measuring the load applied each time the extension is increased. The graph of load versus extension is shown in Figure 6.

Use the graph to find the work done in extending the spring up to Point B.
