Question

4.
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 experim-ental 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.
1) 3.002 x 1011N/m2
2) 1.002 x 10 N/m2
3) 2.002 x 1011N/m2
4) 2.5 x 1011N/m​

Answer 1
