When a metal wire of area of cross-section 1.5×10−6m2 is subjected to a tension of 45 N , the decrease in its area of cross-section is 3×10−10m2. If the Poisson's ratio of the material of the wire is 0.4 , the Young's modulus of the material of the wire is

0.9×1011Nm−2
1.8×1011Nm−2
1.2×1011Nm−2
1.5×1011Nm−2
