Give the expression for the excess pressure in a soap bubble in air.
Give the expression for the excess pressure in a liquid drop.
When a soap bubble of radius 0.2 mm is charged it experiences an outward electrostatic pressure of magnitude sigma^(2)/(2epsilon_(0)) , where sigma=20muCm^(-2) is the surface charge density. If the excess pressure inside the soap bubble due to the tension is same as this electrostatic pressure then the surface tension of the soap solution is (epsi_(0)=8.85xx10^(-12)C^(2)N^(-1)m^(-1))
Why the excess pressure in a soap bubble is more than that of in a water drop?
