cm and 0 004 m formed of the same liquid surface tension 0 07 N m come together to form a double bubble Find the radius and the sense of curvature of the internal film surface common to both the bubbles Sol Let R be the radius of curvature of common surface when bubbles A and B of radii R and RB coalesce The excess pressure in A and B are 4T R and 4T Rg respectively A 4T PA RA and PB 4T R B
