A steel wire of length $2.20\ \text{m}$ is joined to a battery, as illustrated. The voltmeter shows $1.50\ \text{V}$, while the ammeter shows $4.90\ \text{A}$. Steel has a resistivity of $6.90 \times 10^{-7}\ \Omega\,\text{m}$. Determine the diameter of the steel wire.
- A$1.76 \times 10^{-4}\ \text{m}$
- B$3.52 \times 10^{-4}\ \text{m}$
- C$1.26 \times 10^{-3}\ \text{m}$
- D$2.51 \times 10^{-3}\ \text{m}$
