Longitudinal stress of

1N/m{m^2}

is applied on a wire. The percentage increase in length is

\left( {Y = {{10}^{11}}N/{m^2}} \right)

View answer and explanation

Correct option: B

0.001

Option B (

0.001

) is correct because the percentage increase in length is calculated using the formula relating stress, Young's modulus, and strain.
