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_(1) is placed on another soap bubble of radius r_(2)(r_(1) lt r_(2)) . The radius R of the soapy film separating the two bubbles is :

A soap bubble of radius R is surrounded by another soap bubble of radius 2R, as shown. Take surface tension = S.

A soap bubble of raidus R is surrounded by another soap bubble of radius 2R , as shown. Take surface tension =S . Then the pressure inside the smaller soap bubble, in excess of the atmosphere presure will be

A soap bubble of raidus R is surrounded by another soap bubble of radius 2R , as shown. Take surface tension =S . Then the pressure inside the smaller soap bubble, in excess of the atmosphere presure will be

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.

A soap bubble A of radius 0.03 m and another bubble B of radius 0.04 m are brought together, so that the combined bubble has a common interface of radius r, then the value of r is
