Calculating String Mass per Unit Length: Tension, Wave Speed, and Gravity

[gansta344u]

Homework Statement

Tension is maintained in a string as in the
figure. The observed wave speed is 26 m/s
when the suspended mass is 3.2 kg .What is the mass per unit length of
the string? The acceleration of gravity is
9.8 m/s2 . Answer in units of kg/m

The Attempt at a Solution

can someone please guide me in the direcxtion of which i should approach the problem because I am really confused

There is an equation for wave speed on a string. It has to do with tension and mass-per-length, and should be in your textbook.

 

[gansta344u]

do u mean v=frequency(wave length)

 

[Redbelly98]

No, not that one. It should involve the string's tension, as well as the mass-per-unit-length.

its okay i figured it out
