Discuss the below:
Q: Two hydrophobic glass slides measuring 1 cm x 1 cm x 1 mm are floating on water with their sides parallel to each other. Estimate the force of interaction between the solids as a function of their separation distance. Assume that the intrinsic contact angle of the water is 110 degrees.
Intrinsic contact angle is that if you put a drop of water on the slides, the contact angle of the water against the slide would be 110 degrees.
