If the stress applied is equal to the Young's modulus of the material of the wire, the final length of the wire is equal to

A

original length of wire

B

half the original length of wire

C

twice the original length of the wire

D

four times the original length of the wire.

Text Solution

Verified by Experts

The correct Answer is:
C
`Y=F/A xx (L)(l)` when `F/A=Y implies l=L` then final length=2L.
