A transverse wave is propagating on a stretched string of mass per unit length $32 g m^{- 1}$ . The tension on the string is $80 N$ . The speed of the wave over the string is

Options:

Answer:

Solution:

Speed of wave in a string,

$v = \sqrt{\frac{T}{μ}}$

Given, $T = 80 N$

$μ = 32 g m^{- 1}$

$= 32 \times 10^{- 3} kg m^{- 1}$

$v = \sqrt{\frac{80}{32 \times 10^{- 3}}} = \sqrt{\frac{8 \times 10^{4}}{32}}$

$= 100 \times \frac{1}{2}$

$= 50 m s^{- 1}$
