• A force of $200 N$ is applied at one end of a wire of length $2 m$ and having area of cross-section ${{10}^{-2}}\,c{{m}^{2}}$. The other end of the wire is rigidly fixed. If coefficient of linear expansion of the wire $\alpha =8\times {{10}^{-6}}/{}^\circ C$ and Young's modulus $Y=2.2\times {{10}^{11}}\,N/{{m}^{2}}$ and its temperature is increased by 5°C, then the increase in the tension of the wire will be
