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 ).

A capillary tube of diameter 0.6 mm dipped vertically into water. It rises to height of 6 cm in capillary tube, find the surface tension of water. (Given: density of water = 1000 kg//m^3, g = 9.8 m//s^2 ).

When two capillary tubes of different diameters are dipped vertically in a liquid , the rise of the liquid in the capillary tube

Find the surface area of sphere of radius 7 cm.

Calculate the radius of capillary tube if water rise to a height 4.5 cm . Surface tension of water is 72 dyne /cm .

In a capillary tube of radius 'R' a straight thin metal wire of radius 'r' ( Rgtr) is inserted symmetrically and one of the combination is dipped vertically in water such that the lower end of the combination Is at same level . The rise of water in the capillary tube is [T=surface tensiono of water rho =density of water ,g =gravitational acceleration ]

A capillary tube with very thin walls is attached to the beam of a balance which is then equalized. The lower end of the capillry is brought in contact with the surface of water after which an additional load of P = 0.135 gm force is needed to regain equilibrium. If the radius of the capillary is (lambda)/(10)cm then find lambda The surface tension of water is 70 "dyne"//"cm" . (g = 9.8 m//s^(2))

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

A glass capillary tube of radius r is placed vertically touching the surface of water. The water rises to height h in capillary tube. If now the tube is dipped into water till only h/2 length of it is outside the water surface the , radius of curvature of the meniscus of water in capillary tube will be,

A capillary tube of radius r is immersed in water and water rises in to a height h. The mass of water in the capillary tube is 5g. Another capillary tube of radius 2 r is immersed in water. The mass of water that will rise in this tube is
