Forces acting on body placed in meniscus

  1. Sep 4, 2013 #1
    I have a question regarding forces in meniscus.

    Lets assume we have capillary 1cm in diameter. We pour some water into the capillary.
    We will observe concave meniscus. If we add some water (so water level exceed the height of the capillary) we will observe convex meniscus.

    Not lets assume we place a body (not heavy one) on the water surface in the center of the meniscus. What forces (strength and direction) will be acting on our body in both cases?

    Which meniscus can hold heavier body on the water surface?

    Will it change a lot with capillary diameter?

    I hope my question is clear.

    interfacial energy is not related to canthotaxis; the 'floating' body knows nothing of the contact angle.

    Does pressure or temperature change the meniscus of water?

    Can anything change meniscus?
