A copper wire whose diameter is $1.6\,\text{mm}$ is extended, while remaining within its limit of proportionality, by a tensile force of $430\,\text{N}$. The Young modulus of copper is $130\,\text{GPa}$. Determine the strain in the wire.
- A$4.1 \times 10^{-4}$
- B$1.3 \times 10^{-3}$
- C$1.6 \times 10^{-3}$
- D$5.2 \times 10^{-3}$
