A sonometer wire of density

\rho

and radius

{r}

is held between two sharp edges at a distance '

l

'. The wire has a tension

\mathrm{T}

. The frequency of

p

th overtone will be

View answer and explanation

Correct option: D

n=\frac{1}{2 l} \sqrt{\frac{T}{\pi r^2 \rho}}

Option C (

n=\frac{p}{2 l} \sqrt{\frac{T}{\pi r^2 \rho}}

) is correct because the frequency of the pth overtone is p times the fundamental frequency, and the linear density is related to the radius and density.
