Main Question or Discussion Point

the height upto which liquid rises in capillary tube is 2S cosθ / ρgR
I need a derivation for this - please
I know that a combination of adhesive force , surface tension and weight creates the contact angle θ but how to proceed after that?
To calculate height h i need to know the force by which tube is pulling the liquid(adhesive force) but how can i know that?

Its really important for me to know the derivation so plz help me
