B46 Two copper wires A and B, of the same known arcas of cross-section, are subjected to mea- sured stretching forces and the corresponding extensions are measured. The results, on a force-extension graph, are shown in the diagram below. Force N Extonsion/em Explain what deduction you could make about the difference between the two wires. Define the quantities which you would plot to get the same graph for both wires. How would you use this second graph to evaluate an important physical constant of copper? [L)
