The mass and length of a wire are $M$ and $L$ respectively. The density of the material of the wire is $d$. On applying a force $F$ on the wire,the increase in length is $l$. Then,the Young's modulus of the material of the wire will be:
- A$\frac{Fdl}{Ml}$
- B$\frac{FL}{Mdl}$
- C$\frac{FMl}{dl}$
- D$\frac{Fd{L^2}}{Ml}$
