water rises up to the top of the capillary tube and stays there without overflowing.

(C) The height to which water rises in a capillary tube is given by $h = \frac{2T \cos \theta}{r \rho g}$.If the actual length of the tube $L$ is less than the equilibrium height $h$,the water will rise to the top of the tube.At the top,the radius of curvature $R$ of the meniscus will adjust such that $h' = \frac{2T \cos \theta'}{R \rho g} = L$,where $h' Since the pressure at the top remains balanced by the surface tension,the water will not overflow but will stay at the top of the tube with a modified radius of curvature.

When a capillary tube is immersed in water vertically,water rises to a height $h$ inside the tube. If the radius of another capillary tube is $\frac{1}{3}$ that of the previous,the height to which water will rise in this tube is:

$A$ glass capillary tube of inner diameter $0.28 \,mm$ is lowered vertically into water in a vessel. The pressure to be applied on the water in the capillary tube so that the water level in the tube is the same as that in the vessel is ............ $\times 10^3 \,N/m^2$ (surface tension of water $= 0.07 \,N/m$ and atmospheric pressure $= 10^5 \,N/m^2$).
