Mechanics behind capillary depression.
As the question states I have hard time understanding that how does a liquid reach equilibrium in case of capillary depression (mercury for example ). I know how it goes down but not how it 'stops'.
like in case of liquids which have more force of adhesion ,as the liquid goes up because of the forces, it's balanced by it's own weight.
what balances the force pulling mercury down? details please?
