• 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
