A spherical soap bubble of radius 2 cm attached to the outside of a spherical bubble of radius 4 cm. Find the radius of curvature of the common surface.

Two soap bubbles of radius r_(1) and r_(2) combine. Find radius of curvature of the common surface separating them.

A spherical soap bubble A of radius 2 cm is formed inside another bubble B of radius 4 cm. Show that the radius of a single soap bubble which maintance the same pressure difference as inside the smaller and outside the larger soap bubble is lesser than radius of both soap bubbles A and B.

Two soap bubbles each of radius r are touching each other. The radius of curvature of the common surface will be:

Two soap bubbles each of radius r are touching each other. The radius of curvature of the common surface will be:

A soap bubble of radius r is placed on another bubble of radius 2r . The radius of the surface common to both the bubbles is

A soap bubble of radius r is placed on another bubble of radius 2r . The radius of the surface common to both the bubbles is

A spherical soap bubble of radius 1 cm is formed inside another of radius 4 cm. The radius of single soap bubble which maintains the same pressure difference as inside the smaller and outside the larger soap bubble is_____cm.
