Find the speed of a transverse wave along a string of linear density 3

1.	Find the speed of a transverse wave along a string of linear density 3.6 × 10-3 kg/m, when it is under a tension of 1.8 kg wt.
Answer» Data : m = 3.6 × 10^-3 kg/m, g = 9.8 m/s² ∴ T = 1.8 kg wt = 1.8 × 9.8N The speed of transverse waves along the string is v = \(\sqrt{\frac Tm}\) = \(\sqrt{\frac {1.8\times9.8}{3.6\times10^{-3}}}\) = 70 m/s

Find the speed of a transverse wave along a string of linear density 3.6 × 10-3 kg/m, when it is under a tension of 1.8 kg wt.

Answer»

Data : m = 3.6 × 10^-3 kg/m, g = 9.8 m/s²

∴ T = 1.8 kg wt = 1.8 × 9.8N

The speed of transverse waves along the string is

v = \(\sqrt{\frac Tm}\) = \(\sqrt{\frac {1.8\times9.8}{3.6\times10^{-3}}}\) = 70 m/s
