Answer:
The tension will be "713 N".
Explanation:
The given values are:
Frequency,
= 890 Hz
Mass,
= 90 gm
or,
= 0.09 kg
Length of wire,
= 1.0 m
Wavelength,
= 0.10 m
The velocity will be:
= [tex]Frequency\times Wavelength[/tex]
= [tex]890\times 0.10[/tex]
= [tex]89 \ m/s[/tex]
Now,
The tension will be:
⇒ [tex]T=v^2\times \frac{M}{L}[/tex]
On substituting the values, we get
⇒ [tex]=(89)^2\times \frac{0.09}{1.0}[/tex]
⇒ [tex]=7921\times \frac{0.09}{1.0}[/tex]
⇒ [tex]=7921\times 0.09[/tex]
⇒ [tex]=713 \ N[/tex]
