Radius of a capillary is `2xx10^(-3)m`. A liquid of weight `6.28xx10^(-4)N` may remain in the capillary, then the surface tension of liquid will be:

The radius of a capillary tube is 1.4 mm . Water of weight 6.28 xx 10^(-4) N rises in the capillary tube, when it is dipped vertically in water . What is the surface tension of water ?

Give the expression for surface tension of a liquid in a capillary tube.

The weight of liquid column in a capillary tube is 11xx10^(-4)N . If the radius of tube is 7 mm, calculate the surface tension of liquid.

What is capillarity? Obtain an expression for the surface tension of a liquid by capillary rise method.

A capillary tube of radius r can support a liquid of weight 6.28xx10^(-4)N . If the surface tension of the liquid is 5xx10^(-2)N//m . The radius of capillary must be
