The elastic energy stored in a wire of Young’s modulus

Y

View answer and explanation

Correct option: B

\frac{{{{\left( {\mathrm{stress}} \right)}^2}\,\, \times \,\,\mathrm{volume}}}{{2\,Y}}

Option B (

\frac{{{{\left( {\mathrm{stress}} \right)}^2}\times \\,\mathrm{volume}}}{{2\\,Y}}

) is correct because it represents the elastic energy stored in a wire in terms of stress, volume, and Young's modulus.
