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

stress acting on it

Text Solution

Verified by Experts

The correct Answer is:
B
Young.s modulus of materail `Y= ("stress")/("strain")`
If strain is equal to unity, then
Y= stress produced
