A Copper wire of length 2.2m and a steel wire of length 1.6m, both of diameter 3.0mm are connected end to end. When stretched by a load, the net elongation is found to be 0.70 mm. Obtain the load applied . Young's modulus of copper is 1.1 xx 10^(11)Nm^(-2) and Young's modulus of steel is 2.0 xx 10^(11)Nm^(-2).
want a explaination how delta l c become 5 into 10 ^ - 4 m and delta l s become 2 into 10 ^ - 4 m
