Two persons pull a wire towards themselves. Each person exerts a force of $\displaystyle 200$ N on the wire. Young's modulus of the material of wire is $\displaystyle 1 \times 10^{11} \mathrm{~N} \mathrm{~m}^{-2}$. Original length of the wire is $\displaystyle 2$ m and the area of cross section is $\displaystyle 2 \mathrm{~cm}^2$. The wire will extend in length by $\displaystyle \_\_\_\_$ $\displaystyle \mu \mathrm{m}$.
