Two soap bubbles of radii 2 cm and 4 cm join to form a double bubble in air, then radius of. curvature of interface is

Two soap bubbles of radii 2 cm and 3 cm are brought in contact. Find the radius of curvature (in cm) of the contact surface.

Two soap bubbles of radii 2 cm and 3 cm are brought in contact. Find the radius of curvature (in cm) of the contact surface.

Two soap bubble of radius 2r and 3r are in contact with each other. If the radius of curvature of the interface between the bubble in nr then find the value of n :

Two soap bubble of radii 3 mm and 4 mm are in contact radius of curvature of interface between those two bubbles is

Two bubbles of radii 2mm and 3mm when touch each other, the radius of curvature of their interface is

Two soap bubbles of radii r_1 and r_2 combine to form a bigger bubble under isothermal conditions. The radius of bigger bubble will be
