The shape of liquid meniscus is concave. Will it rise or fall in a capillary tube?

The spherical shape of liquid drops is due to

How is the rise of a liquid affected if the top of the capillary tube is closed?

A glass convex lens has a power of +10 D.When ths lens is totally immersed in a liquid,it acts as concave lens of focal length 50cm.Calculate the refractive index of the liquid.Given ^a mu_g=1.5 .

The mensicus of a liquid contained in one of the limbs of a narrow U-tube is held in an electromagnetic with the mensicus in line with the field . The liquid is seen to rise . This indicates that the liquid is

Derive an expression for the rise of liquid in a capillary tube and show that the height of the liquid column supported is inversely proportional to the radius of the tube.
