In a capillary tube having area of cross-section $A$,the water rises to a height $h$. If the cross-sectional area is reduced to $\frac{A}{9}$,the rise of water in the capillary tube is

When a capillary is dipped in water,water rises to a height $h$. If the length of the capillary is made less than $h$,then

The sap in a tree rises in a system of capillaries of radius $2.5 \times 10^{-5} \, m$. The surface tension of the sap is $7.28 \times 10^{-2} \, N \, m^{-1}$ and the angle of contact is $0^{\circ}$. The maximum height to which the sap can rise in a tree through capillarity action is ...... $m$ (take $\rho_{sap} = 10^3 \, kg \, m^{-3}$ and $g = 9.8 \, m \, s^{-2}$).

Water rises to height $h$ in a capillary tube. If the length of the capillary tube above the surface of water is made less than $h$,then

Two capillary tubes made of the same material are dipped in the same liquid. If the heights of the liquid in the tubes are $2.2 \ cm$ and $6.6 \ cm$ respectively,what is the ratio of their radii?

Water rises in a vertical capillary tube up to a height of $2.0 \, cm$. If the tube is inclined at an angle of $60^{\circ}$ with the vertical,then up to what length will the water rise in the tube?
