When a wire of length 10m is subjected to a force of 100N along its length, the lateral strain produced is 0.01 x 10 The Poisson's ratio was found to be 0.4. If the area of cross-section of wire is 0.025m then its Young's modulus is
a.1.6 x 10⁸N/m²
b. 2.5 x 10¹⁰ N/m²
c. 12,5 x 10¹¹ N/m²
d. 16 x 10⁹ N/m²
