Answer:
[tex]T =87.87\ N[/tex]
Explanation:
Given,
Length , l=2.89 m
Mass , M=0.258 Kg
Now, displacement [tex]d=4(2 \times 2.89) m[/tex]
[tex]=23.12 m[/tex]
Velocity of waves
[tex]v=\sqrt{T / \mu}[/tex]
[tex]\mu=\frac{0.258}{2.89 }[/tex]
[tex]=0.0893[/tex]
Now, velocity, [tex]v=\frac{d}{t}=\frac{23.12}{0.737 s}[/tex]
[tex]=31.37 m/s[/tex]
The tension
[tex]T=v^{2} \mu=31.37 \times 31.37 \times 0.0893[/tex]
[tex]T =87.87\ N[/tex]
Tension in the chord is equal to [tex]T =87.87\ N[/tex]
