Excess pressure inside a soap bubble of radius r and surface tension T is

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.

Surface charge density of soap bubble of radius r and surface tension T is sigma .If P is excess pressure the value of sigma is
