what is the excess pressure inside a bubble of soap solution of radius 5 mm .Give surface tension of soapis 2.5*10^-2 n/m. if an air bubble of same diamension is formed at depth of 40cm.inside the container containing the soap solution.what is the pressure inside tha bubble. density of soap solution is 1.2
The excess pressure inside the air bubble is given by the relation:
P =2S/r
At a depth of 0.4 m, the total pressure inside the air bubble
= Atmospheric pressure + h?g + P
