A coaxial cylinder made of glass is immersed in a-liquid of surface tension S. The radius of the inner and outer surface of the cylinder are `R_1 and R_2` respectively . Height till which liquid will rise is (Density of liquid is `rho` )

A needle of length l and density rho will float on a liquid of surface tension sigma if its radius r is less than or equal to:

A needle of length l and density rho will float on a liquid of surface tension sigma if its radius r is less than or equal to:

Drops of liquid of density d are floating half immersed in a liquid of density p. If the surface tension of the liquid is T, then the radius of the drop is

A vertical U-tube contains a liquid of density rho and surface tension T. if the radius of the meniscus of liquid in the limbs of the U-tube are R_(1) and R_(2) find the difference in the liquid column in the limbs.

A capillary tube of radius r is lowered into a liquid of surface tension T and density rho . Given angle of contact =0^(@) . The work done by surface tension will be

When a capillary tube of radius 'r' is dipped vertically in a liquid of surface tension T, the liquid rises to a height 'h' in the tube above the level outside the tube. If the angle of contact is theta , the density of the liquid is rho , then the pressure difference is.

The time period (t) of vibration of a liquid drop depends on surface tension (s),radius ( r) of the drop and density (rho) of the liquid .Find t.
