A small spherical droplet of density d is floating exactly half immersed in a liquid of density `tho` and surface tension T. The radius of the droplet is (take note that the surfacfe tension applied an upward force on the droplet):

`sqrt(T/((rho-sigma)g))`

`sqrt(T/((rho-2sigma)g))`

`sqrt(2T/((2rho-3sigma)g))`

`sqrt(3T/((2rho-sigma)g))`
