Which one of the following relations is dimensionally consistent where h is height to which a liquid of density $\rho$ rises in a capillary tube of radius r, T is the surface tension of the liquid, θ the angle of contact and g the acceleration due to gravity |
$h=\frac{2 T \cos \theta}{r \rho g}$ $h=\frac{2 T r}{\rho g \cos \theta}$ $h=\frac{2 \rho g \cos \theta}{2Tr}$ $h=\frac{2Tr \rho g}{\cos \theta}$ |
$h=\frac{2 T \cos \theta}{r \rho g}$ |
