Question

A steel wire with mass per unit length \( 7.0 \times 10^{-3} \, \text{kg/m} \) is under a tension of \( 70 \, \text{N} \). The speed of transverse waves in the wire will be:

• A. \( 100 \, \text{m/s} \)
• B. \( 50 \, \text{m/s} \)
• C. \( 10 \, \text{m/s} \)
• D. \( 200 \pi \, \text{m/s} \)

Hint:

The speed of transverse waves in a wire increases with the square root of the tension and decreases with the square root of the mass per unit length. Ensure accurate substitution and unit consistency for reliable results.
