In the Searle's method to determine the Young's modulus of a wire, a steel wire of length 156 cm and diameter 0.054 cm is taken as experimental wire. The average increase in length for 1 1/2 kg wt is found to be 0.050 cm. Then the Young's modulus of the wire.

Options

A. `3.002 xx 10^11 N//m^2`

C. `2.002 xx 10^11 N//m^2`
D. `2.5 xx 10^11 N//m^2`
