Longitudinal stress of 1 kg//mm^(2) is a...

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

0.01

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Longitude strain `=("stress")/(Y)=(10^(6))/(10^(11))=10^(-5)`
Percentage increase in length `=10^(-5)xx100=0.001%`
