A steel wire of length $3.2\mathrm{m}\left({\mathrm{Y}}_{\mathrm{S}}=2.0\times {10}^{11}{\mathrm{Nm}}^{-2}\right)$ and a copper wire of length 4.4 m$\left({\mathrm{Y}}_{\mathrm{C}}=1.1\times {10}^{11}{\mathrm{Nm}}^{-2}\right)$, both of radius 1.4 mm are connected end to end. When stretched by a load, the net elongation is found to be 1.4 mm. The load applied, in Newton, will be: $\left(\text{ Given }\mathrm{\pi }=\frac{22}{7}\right)$
