A material has Poisson's ratio 0.50.If a uniform rod of it suffers a longitudinal strain of 2times10^-3 ,then the percentage change in volume is

A

`0.6`

B

`0.4`

C

`0.2`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
`(Delta V)/(V) = (1-2 xx sigma) (Delta l)/(l) rArr (Delta V)/(V)= 0` (here `sigma= 0.5`)
