Question

if surface tension and radius of liquid 6.2×10—²N/m and 10m then excess pressure in spherical drop is

​

Answer 1

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.
