It is desired to measure the Young's modulus and the Poisson's ratio of a given homogeneous, isotropic material. A bar of length 20cm and square cross-section (10mm×10mm) of this material is subjected to a tensile load of 40kN. Under this load, length increases to 20.1cm while the cross-section reduces to 9.98mm×9.98mm Young's modulus and Poisson's ratio of the material are:
A
80GPa& 0.4 respectively
B
40GPa& -0.4 respectively
C
80GPa& -0.2 respectively
D
40GPa& 0.2 respectively

Correct : a
