The adjacent graph shows the extension \( (\Delta l) \) of a wire of length \( 1 \mathrm{~m} \) suspended from the top of a roof at one end with a load \( W \) connected to the other end. if the corsssectional area of the wire is \( 10^{-6} \mathrm{~m}^{2} \), calculate the Young's modulus of the material of the wire
(a) \( 2 \times 10^{11} \mathrm{~N} / \mathrm{m}^{2} \)
(b) \( 2 \times 10^{-11} \mathrm{~N} / \mathrm{m}^{2} \)
(c) \( 2 \times 10^{-12} \mathrm{~N} / \mathrm{m}^{2} \)
(d) \( 2 \times 10^{-13} \mathrm{~N} / \mathrm{m}^{2} \)
