Longitudinal stress of `1 kg//mm^(2)` is applied on a wire. The percentage increase in length is `(Y = 10^(11) N//m^(2))`

A

`0.002`

B

`0.001`

C

`0.003`

D

`0.001`

Text Solution

Verified by Experts

The correct Answer is:
B
Strain `=(DeltaL)/(L)=("stress")/(Y)`
`%` increase `=10^(-5)xx100=0.001`
