The excess pressure in a soap bubble is thrice that in other one. Then the ratio of their volume is
When two capillary tubes of different diameters are dipped vertically, the rise of the liquid is
Due to capillary action, a liquid will rise in a tube, if the angle of contact is
In the state of weightlessness, a capillary tube is dipped in water, then water
Two parallel glass plates are dipped partly in the liquid of density $d$ keeping them vertical. If the distance between the plates is $x$, surface tension for liquids is $T$ and angle of contact is $\theta$, then rise of liquid between the plates due to capillary will be
Water rises in a capillary tube to a certain height such that the upward force due to surface tension is balanced by $75\times {{10}^{-4}}N$ force due to the weight of the liquid. If the surface tension of water is $6\times {{10}^{-2}}\,N{{m}^{-1}}$, the inner circumference of the capillary must be
It is not possible to write directly on blotting paper or newspaper with ink pen
Two capillary tubes P and Q are dipped in water. The height of water level in capillary P is 2/3 to the height in Q capillary. The ratio of their diameters is
Two capillaries made of same material but of different radii are dipped in a liquid. The rise of liquid in one capillary is 2.2 cm and that in the other is 6.6 cm. The ratio of their radii is
Two capillaries made of the same material with radii ${{r}_{1}}=1mm$ and ${{r}_{2}}=2mm$. The rise of the liquid in one capillary (${{r}_{1}}=mm$) is 30 cm, then the rise in the other will be
