The unit of Young's modulus is

\left[\mathrm{Y}=\frac{\text {Stress}}{\text {Strain}}=\frac{\text {force} / \text {area}}{\Delta \ell / \mathrm{L}}\right]

View answer and explanation

Correct option: C

Newton/metre

{ }^2

Option C (Newton/metre

{ }^2

) is correct because Young's modulus is defined as stress/strain, where stress has units of force/area (N/m²) and strain is dimensionless.
