Contact angle of liquid drop on solid surface.
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/EAMCE...0_198-208_.pdf) How is the surface tension direction found out? Also why is surface tension for Solid-Air Surface considered when balancing forces on liquid? Any help will be appreciated Thank you. |

direction will be tangential to both interfaces.
