Question

Obtain the formula of maximum surface charge density for equilibrium of charged soap bubble.
Answer.
Equilibrium Condition for Charged Soap Bubble
The pressure of air on the internal surface of the soap bubble is more than that the atmospheric pressure present on the external surface. This pressure is balanced by the force of surface tension. If the radius of the bubble is r and surface tension is T, then the excess pressure is

Answer 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.
