PhysicsEasysingle choice

Two wires, made up of same material, are of equal lengths but their radii are in the ratio $1 : 2$ . On stretching each of these two string by the same tension, the ratio between their fundamental frequencies is

Options:

Answer:

Solution:

Here, $ρ_{1} = ρ_{2}; \frac{r_{1}}{r_{2}} = \frac{1}{2}, T_{1} = T_{2}$

$n_{1} = \frac{1}{2 l r_{1}} \sqrt{\frac{T_{1}}{π ρ_{1}}}; n_{2} = \frac{1}{2 l r_{2}} \sqrt{\frac{T_{2}}{π ρ_{2}}}$

$\frac{n_{1}}{n_{2}} = \frac{r_{2}}{r_{1}} = 2$
