Two soap bubbles are joined together so that they have a common surface. If their radii are 3 cm and 4 cm respectively, find the radius of the common surface.

When two soap bubbles of radii a and b ( b gt a ) coalesce, the radius of curvature of common surface is :

Two soap bubbles with radius 2r and 3r come in contact. Their common surface has a radius of curvature nr , then find the value of n

When two soap bubbles of radii r_1 and r_2 ( r_2>r_1 )coalese, the radius of curvature of common surface is

Two soap bubbles coalesce.It noticed that, whilst joined together, the radii of the two bubbles are a and b where agtb.Then the radius of curvature of interface between the two bubbles will be

Two soap bubbles coalesce.It noticed that, whilst joined together, the radii of the two bubbles are a and b where a>b.Then the radius of curvature of interface between the two bubbles will be
