A `3cm` long copper wire is strechted to increases its length by `.3cm`. Find the laterial strain in the wire, if the possion's ratio for copper is `0.26`

A

`0.013`

B

`0.018`

C

`0.026`

D

`0.016`

Text Solution

Verified by Experts

The correct Answer is:
C
`sigma = ("lateral strain")/("Longitudinal strain")`
The Lateral Strain `= sigma xx` Longitudinal Strain
