Two vertical parallel glass plates , separated by 0.5 mm, are kept in water . The surface tension of water is `7 xx 10^(-2)` N/m . How high will the water rise between the plates ? (use g = `10 "m/s"^(2)`)

A glass rod of radius 1 mm is inserted symmetrically into a glass capillary tube with inside radius 2 mm . Then the whole arrangement is brought in contact of the surface of water. Surface tension of water is 7 xx 10^(-2) N//m . To what height will the water rise in the capillary? ( theta = 0^@ )

When a capillary is dipped in water, water rises 0.015 m in it. If the surface tension of water is 75 xx 10^(-3) N//m , the radius of capillary is

Two vertical, parallel glass plates are partially submerged in water. The distance between the plates is d=100 mum , their length is l=10 cm. Assuming that the water between the plates does not reach the upper edge of the plates and that the wetting is complete, find the force of attraction, indicating how the force arises. Surface tension of water =73m N/m.

Two vertical parallel glass plates are partically submerged in water. The distance between the plates is d=0.10mm , and their width is l=12cm assuming that the water between the plates does not reach the upper edges of the plates and the wetting is complete. Find the force of their mutual attraction

Two vertical parallel glass plates are partially submerged in water. The distance between the plates is d and the length is l . Assume that the water between the plates does not reach the upper edges of the plates and the plates and the wetting is complete. The water will rise to height ( rho= density of water and alpha = surface tension of water)
