Aguitar string of length l = 0.79 m is oriented along the x-direction and under a tension of t = 74 n. the string is made of steel which has a density of rho = 7800 kg / m3. the radius of the string is r = 8.5 x 10-4 m. a transverse wave of amplitude a = 0.0020 m is formed on the string. find the string tension.

74 N

Explanation:

T = Tension in the string = 74 N

= Density of the steel = 7800 kg/m³

A = Area =

r = Radius =

Linear density is given by

The linear density is 0.0177 kg/m

Velocity is given by

The velocity of the wave on the guitar string is 64.65903 m/s

think its the third option

this is poiselle's equation from fluid mechanic in physics. mech eng
