What is the excess pressure inside a bubble of soap solution of radius 5.00 mm , given that the surface of soap solution at the temperature `(20^(@)C)` is `2.50xx10^(-2)Nm^(-1)` ? If an air bubble of the same dimension were formed at depth of 40.0 cm inside a container containing the soap solution (of relative density 1.20) , what would be the pressure is `1.01xx10^(5)Pa)`.
