force = S.dl
S = surface tension
dl = small length particle
also
P = S/R
S=PR
dimension of S
= MT-²
S = surface tension
dl = small length particle
also
P = S/R
S=PR
dimension of S
= MT-²

It has no component perpendicular to the horizontal surface. As a result, there is no pressure difference between the liquid side and the vapour side. ... Thus, there is always an excess of pressure on the concave side of a curved liquid surface over the pressure on its convex side due to surface tension.
