Contact angle of liquid drop on solid surface.2

  1. Feb 15, 2013 #1
    Can anyone explain point 44 of the attached pdf document on surface tension.

    (Here's the link in case attachment doesn't work:
    http://www.sakshieducation.com/EAMCET/QR/Physics/Jr Phy/12Surface tension _198-208_.pdf

    How is the surface tension direction found out?
    {i know it tangential but in which direction along the tangent?}
    Also why is surface tension for Solid-Air Surface considered when balancing forces on liquid?
    Any help will be appreciated
    Thank you.
