The adjacent graph shows the estension `(Deltal)` of a wire of length 1m suspended from the top of a roof at one end and with a load W connected to the other end. If the cross-sectional area of the wire is `10^-6m^2`, calculate the Young's modulus of the material of the wire.

`2xx10^(11) N//m^(2)`

`3xx10^(12) N//m^(2)`
