If we dip capillary tubes of differnt radii r in water and water rises to different height h in them, then

Take a few containers of different sizes with circular bases. Fill the same amount of water in each container . Note the diameter of each container and the respective height at which the water level stands . Tabulate your observations. Is it a case of inverse proportion?

Two narrow bores of diameters 3.0 mm and 6.0 mm are joined together to form a U-tube open at both ends. If the U-tube contains water, what is the difference in its levels in the two limbs of the tube ? Surface tension of water at the temperature of the experiment is 7.3xx 10^-2 N m^-1 '. Take the angle of contact to be zero and density of water to be 1.0xx 10^3 kg m^- 3 ( g = 9.8 m s^-2 ) .

Water rises to a height of 9 cm in a capillary tube.To what height the water will rise in another capillary tube having dimeter 1//3 of the first ?

The radius of a capillary tube is doubled. What changes will take place in height of the capillary rise?

In the previous problem, if 15.0 cm of water and spirit each are further poured into the respective arms of the tube, what is the difference in the levels of mercury in the two arms ? (Specific gravity of mercury = 13.6)
