The young's modulus of a wire of length $\mathrm{L}$ and radius $\mathrm{r}$ is $\mathrm{Y}\left(\mathrm{N} / \mathrm{m}^{2}\right)$. If the length and radius are reduced to $\mathrm{L} / 2$ and $\mathrm{r} / 2$. Then what will be its young's modulus? (A) $\mathrm{Y} / 2$ (B) $\mathrm{Y}$ (C) $2 \mathrm{Y}$ (D) $4 \mathrm{Y}$
The young's modulus of a wire of length ' L ' and radius ' r ' is ' Y '. If length is reduced to L/2 and radius r/2 , Young's modulus will be : A. Y/2 B. Y C. 2Y D. 4Y
