Application +4 | -1

An elongation of 0.4% in a wire of cross-sectional area is

{10^{ - 6}}\,{m^2}

causes a tension of 100 N. Y for the wire is

[\mathrm{in }\,\,N/{m^2}]

View answer and explanation

Correct option: D

25 \times {10^9}

Option D (

25 \times {10^9}

) is correct because Young's modulus is calculated by dividing stress by strain.
