A glass rod of radius ' $r$ ' ' is inserted symmetrically into a vertical capillary tube of radius ' ${\mathrm{r}}_2$ ' $\left({\mathrm{r}}_1<{\mathrm{r}}_2\right)$ such that their lower ends are at same level. The arrangement is dipped in water. The height to which water will rise into the tube will be ( $\rho =$ density of water, $\mathrm{T}=$ surface tension in water, $\mathrm{g}$ = acceleration due to gravity)
