The ratio of surface tensions of mercury and water is given to be 7.5 while the ratio of their densities is 13.6. Their contact angles, with glass, are close to 135° and 0°, respectively. It is observed that mercury gets depressed by an amount h in a capillary tube of radius `r_(1)` while water rises the same amount h in a capillary tube of radius `r_(2)`. The ratio, `(r_(1)//r_(2))` , is then close to

If 'M' is the mass of water that rises in a capillary tube of radius 'r', then mass of water which will ris in a capillary tube of radius '2r' is :

Water rises to a height h in a capillary tube of radius r. The mass of water in the capillary tube is 10 g. The mass of water rising in another capillary tube of radius 4r will be

The work done by surface tension on rising water do height of h in a capillary tube of radius r is

Water rises upto a height h in a capillary tube of radius r. What is the network done in this process if the density of water is rho ?

Water rises to a height fo 6 cm in a capillary tube of radius r . If the radius of the capillary tube is 3r, the height to which water will rise is ….cm.

A capillary tube is dipped in water and the water rises in it to a height h . If r be the radius of the bore of the tube , then

Calculate the ratio of surface tension of mercury and water if in a capillary tube, mercury is depressed by 3.45 cm and water rises by 9.8 cm in the same tube. The angle of contact for mercury is 140^@ and that for water is 0^@.
