When a wire of length 10 {\m} is subjected to a force of 100 {\N} along its length, the lateral strain produced is 0.01 \times 10^{-3} {\m}. The Poisson's ratio was found to be 0.4. If the area of cross-section of wire is 0.025 {\m}^2, its Young's modulus is

Correct Answer is : 16×109N∕m2

2.5 \times 10^{10} {\N} \/ {\m}^2

1.25 \times 10^{11} {\N} \/ {\m}^2

When a wire of length 10m is subjected to a force of 100N along its length, the lateral strain produced is 0.01×10−3m. The Poisson's ratio was found to be 0.4. If the area of cross-section of wire is 0.025m2, its Young's modulus is

1.6×108N∕m2
2.5×1010N∕m2
1.25×1011N∕m2
16×109N∕m2
