1. \(7.85\) cm and \(2.09\) s
2. \(7.85\) mm and \(1.09\) s
3. \(7.85\) m and \(0.09\) s
4. none of these

A steel wire \(0.72~\text{m}\) long has a mass of \(5\times10^{-3}~\text{kg}\). If the wire is under tension of \(60~\text{N}\), the speed of transverse waves on the wire will be:
1. \(85~\text{m/s}\)
2. \(83~\text{m/s}\)
3. \(93~\text{m/s}\)
4. \(100~\text{m/s}\)
