Find the height of liquid in capillary tube, if surface tension of liquid \( =S \), radius of capillary tube \( =r \) and acceleration due to gravity \( =g \).
(a) \( \frac{2 S \cos \theta}{\rho r g} \)
(b) \( \frac{2 S}{\rho r g \cos \theta} \)
(c) \( \frac{2 S \sin \theta}{\rho r g} \)
(d) None of these
