A string of linear density 0.2kg/m is stretched with a force of 500 N. If a transverse wave of wavelength 4m and amplitude `(1//pi)` metre is travelling along it, then the speed of the wave will be

50m/s

62.5m/s

12.5m/s

250m/s

Text Solution

Verified by Experts

The correct Answer is:

`v=sqrt(T/m) = sqrt((5000)/(0.2)) = sqrt(2500) = 50m//s`
