An iron rod and a copper rod lie side by side. As the temperature is changed, the difference in the lengths of the rods remains constant at a value of `10cm` . Find the lengths at `0^(@)C` . Coefficient of linear expansion of iron and copper are `1.1xx10^(-5)//^(@)C` and `1.7xx10^(-5)//^(@)C`  respectively.
