Two identical strings X and Z made of same material have tension T_X and T_Z in them. If their fundamental frequencies are 450 Hz and 300 Hz,…
Two identical strings X and Z made of same material have tension $\displaystyle \mathrm{T}_{\mathrm{X}}$ and $\displaystyle \mathrm{T}_{\mathrm{Z}}$ in them. If their fundamental frequencies are $\displaystyle 450$ Hz and $\displaystyle 300$ Hz , respectively, then the ratio $\displaystyle \mathrm{T}_{\mathrm{X}} / \mathrm{T}_{\mathrm{Z}}$ is :

(2)
$\displaystyle 2.25$
