The Young's modulus of the material of a wire is equal ot the

A

stress required to increase its length four times

B

stress required to produce unit strain

C

strain produced in it

D

half the strain produced in it

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Young's modulus of material
`Y=("Linear stress")/("Longitudinal strain")`
If longitudinal strain is equal to unity then, Y=linear stress produced.
