Physics - Wave on String Question with Solution | TestHub

Mass of string $=0.1\mathrm{lgg}$ Tension $T=1.6\mathrm{N}$ Length $\ell =1\mathrm{m}$ Man per unit length $\mu =\frac{m}{1}=\frac{0.1}{1}=0.1\mathrm{kg}/\mathrm{m}$ The velocity $(v)$ of the transverse wave in the string is given by the relation $\begin{array}{rl}V& =\sqrt{\frac{T}{4}}\\ & =\sqrt{\frac{1.6}{0.1}}\\ & =4\mathrm{m}/\mathrm{s}\end{array}$ Time taken $T=\ell /V=1/4=0.25\sec$
