A material is having Poisson's ratio 0.2. A load is applied on it due to which it suffers the longitudinal strain `3xx10^(-3)` , then find out the percentage change in its volume.

Options

A. `1%`
B. `0%`
C. `5%`
D. `7%`

Answer

B

Explanation

`(dV)/(V)= (1- 2 sigma) (dL)/(L)= (1-2 xx (1)/(2)) 3 xx 10^(-2)`
`therefore (dV)/(V) xx 100=0`
