140943 A steel wire of length $1.5 \mathrm{~m}$ can withstand a maximum $1500 \mathrm{~N}$ tension before it breaks. The tensile strength of steel is $5 \times 10^{8} \mathrm{~N} / \mathrm{m}^{2}$. If the same wire is stretched by $0.20 \mathrm{~cm}$ in the elastic limit, the tension in the wire is (Young's modulus of steel $2 \times 10^{11} \mathrm{~N} / \mathrm{m}^{2}$ )
140944 A steel wire of length $20 \mathrm{~cm}$ and area of crosssection $1 \mathrm{~mm}^{2}$ is tied rigidly at both the ends. When the temperature of the wire is changed from $40^{\circ} \mathrm{C}$ to $20^{\circ} \mathrm{C}$, find the change in its tension. Given, the coefficient of linear expansion for steel is $1.1 \times 10^{-5}{ }^{\circ} \mathrm{C}^{-1}$ and Young's modulus of steel is $2.0 \times 10^{11} \mathrm{Nm}^{-2}$.
