A charged soap bobbe having surface charge density `sigma` and radius r. If the pressure inside and outsides the soap bubble is the same, then the surface tension of the soap solution is

What is the excess of pressure inside a soap bubble of radius 3cm if the surface tension of the soap solution is 30 dyn/cm ?

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))

The excess pressure inside a soap bubble of radius R is (S is the surface tension)

Find the difference in air pressure between the inside and outside of a soap bubble 5 mm in diameter , if the surface tension of soap solution be 1.6N/m .

Calculate the excess inside a soap bubble of radius 5mm, given surface tension of soap solution 30 dyne/cm.
