In air, a charged soap bubble of radius 'R' breaks into 27 small soap bubbles of equal radius 'r '. Then the ratio of mechanical force acting per unit area of big soap bubble to that of a small soap bubble is

Two soap bubbles of radius R_1 and R_2 combine isothermally to form a new soap bubble. Find radius of new soap bubble

An air bubble just inside a soap solution and a soap bubble blown using the same solution have the same radii. The ratio of the excess pressure inside the air bubble to that inside the soap bubble is
