Figure represents the extension ( $\displaystyle \Delta l$ ) of a wire of length $\displaystyle 1$ meter, suspended from the ceiling of the room at one end with a load $\displaystyle W$ connected to the other end. If the cross-sectional area of the wire is $\displaystyle 10^{-5} \mathrm{~m}^2$ then the Young's modulus of the wire is $\displaystyle \_\_\_\_$ $\displaystyle \mathrm{N} / \mathrm{m}^2$.
