A capillary tube is held vertically in water . The internal radius of the tube is `(1//42)` cm . If the surface tension is 70 dyne /cm and angle of contact is zero , then rise in the capillary tube is

Internal radius of a capilary tube is (1)/(2)cm and surface tension of water 70 dyne/cm, if angle of contact is zero, then water will rise up in the tube up to height.

If a capillary tube of radius 1 mm is immersed in water , the mass of water rising in the capillary tube is M . If the radius tube is doubled , then the mass of water , that rises in the capillary tube will be

If a capillary tube of radius 1 mm is immersed in water , the mass of water rising in the capillary tube is M . If the radius tube is doubled , then the mass of water , that rises in the capillary tube will be

A capilary tube is kept vertical and made to touch the surface of the liquid of surface tension T . If the radius of the capillary tube is 'r' . Then the force on the wall of the capillary tube is

A capillary tube of radius 'r' is immersed in water and water rises to a height of 'h'. Mass of water in the capillary tube is 5 xx 10^ -3 kg . The same capillary tube is now immersed in a liquid whose surface tension is sqrt2 times the surface tension of water. The angle of contact between the capillarv tube and this liauid is 45^@ . The mass of liquid which rises into the capillary tube now is (in kg)

A capillary tube of uniform bore is dipped vertically in water which rises by 7 cm in the tube. Find the radius of the capillary if the surface tension of water is 70dy//cm .

A capillary tube of uniform bore is dipped vertically in water which rises by 6 cm in the tube. Find the radius of the capillary tube if the surface tension of water is 72 dyne/cm (g= 980 cm//s^2 ).
