A \( 100 \, \text{m} \) long wire having cross-sectional area \( 6.25 \times 10^{-4} \, \text{m}^{2} \) and Young’s modulus is \( 10^{10} \, \text{N m}^{-2} \) is subjected to a load of \( 250 \, \text{N} \), then the elongation in the wire will be:
\( 6.25 \times 10^{-6} \, \text{m} \)
\( 4 \times 10^{-3} \, \text{m} \)
\( 6.25 \times 10^{-3} \, \text{m} \)
\( 4 \times 10^{-4} \, \text{m} \)
