An unstretched wire has a length of $2.00\,\text{m}$. A stress of $1.6 \times 10^{5}\,\text{Pa}$ is applied to the wire, causing its length to become $2.10\,\text{m}$. The wire follows Hooke’s law. What is the Young modulus of the wire?
- A$8.0 \times 10^{3}\,\text{Pa}$
- B$7.8 \times 10^{4}\,\text{Pa}$
- C$1.5 \times 10^{5}\,\text{Pa}$
- D$3.2 \times 10^{6}\,\text{Pa}$
