Question

247.A 5.5m length string has a mass of 0.35kg.If the tension in the string is 77N.The speed of a transverse wave on the string is

Answer 1

Dear student,

Mass per unit length, $\frac{m}{l}=\frac{0.35}{5.5}\mathrm{kg}/\mathrm{m}$
Speed of transverse wave, $v=\sqrt{\frac{T}{\left(\frac{m}{l}\right)}}=\sqrt{\frac{77}{\left(\frac{0.35}{5.5}\right)}}=11\sqrt{10}\mathrm{m}/\mathrm{s}$
Regards.
