A metal wire is $5.2\,\text{m}$ long and has a diameter of $1.0\,\text{mm}$. Its Young modulus is $360\,\text{GPa}$. One end of the wire is held fixed, and a force is exerted on the other end. This force produces an extension of $7.2\,\text{mm}$ in the wire. Assume Hooke’s law applies. What is the force applied to the wire?
- A$1.2 \times 10^2\,\text{N}$
- B$3.9 \times 10^2\,\text{N}$
- C$5.0 \times 10^2\,\text{N}$
- D$1.6 \times 10^3\,\text{N}$
