Young’s modulus depends upon the nature of the material and not on geometrical dimensioris.

Q. The Young’s modulus of a wire of length $L$ and radius $r$ is $Y$ . If the length is reduced to $\frac{L}{2}$ and radius is $\frac{r}{2}$ , then the Young’s modulus will be

$\frac{Y}{2}$

$Y$

$2 Y$

$4 Y$
