Two parallel glass plates are dipped partly in the liquid of density d keeping them vertical. If the distance between the plates is x, the surface tension for the liquid is T and the angle of contact , then the rise of liquid between the plates due to capillary will be:
Let the width of each plate be b and due to surface tension, the liquid will rise up to height h, then upward force due to surface tension
The weight of the liquid rises in between the plate
