A steel wire measures $300\,\text{cm}$ in length and has a cross-sectional area of $0.50\,\text{mm}^2$. Its Young modulus is $2.0 \times 10^{11}\,\text{Pa}$. One end of the wire is fastened to a fixed point, and a load of $10\,\text{N}$ is suspended from the other end. The wire follows Hooke’s law. Determine the extension of the wire.
- A$3.0 \times 10^{-7}\,\text{m}$
- B$3.0 \times 10^{-5}\,\text{m}$
- C$3.0 \times 10^{-4}\,\text{m}$
- D$3.0 \times 10^{-2}\,\text{m}$
