A wire of original length $L$ and cross-sectional area $A$ is subjected to a tensile force $F$, causing an extension of $x$. The wire follows Hooke’s law. What expression gives the Young modulus of the material from which the wire is made?
- A$\frac{\text{stress} \times x}{L}$
- B$\frac{F}{A \times \text{strain}}$
- C$\frac{F \times x}{A \times L}$
- D$\frac{\text{strain}}{\text{stress}}$
