Answer:
Tension in wire will be [tex]16\times 10^3N-m[/tex]
Explanation:
We have given seed of the transverse wave v = 400 m/sec
Linear density = 0.10 g/cm
We know that 1 gram = 0.001 kg
And 1 cm = 0.01 m
So [tex]0.1g/cm =\frac{0.1\times 10^{-3}kg}{10^{-2}m}=10^{-2}kg/m[/tex]
We know that speed of wave is given by [tex]v=\sqrt{\frac{T}{linear\ density}}[/tex], here T is tension in the wire
So [tex]400=\sqrt{\frac{T}{10^{-2}}}[/tex]
Squaring both side [tex]16\times 10^4=\frac{T}{0.1}[/tex]
T = [tex]16\times 10^3N-m[/tex]
So tension in wire will be [tex]16\times 10^3N-m[/tex]
