[" A soap bubble has radius "R" and "],[" thickness "d(<

An isolated and charged spherical soap bubble has a radius 'r' and the pressure inside is atmospheric. If 'T' is the surface tension of soap solution, then charge on drop is:

An isolated and charged spherical soap bubble has a radius 'r' and the pressure inside is atmospheric. If 'T' is the surface tension of soap solution, then charge on drop is:

A soap - bubble with a radius 'r' is placed on another bubbles with a radius R (figure). Angles between the film at the point of contact will be -

A soap - bubble with a radius 'r' is placed on another bubbles with a radius R (figure). Angles between the film at the point of contact will be -

Excess pressure inside a soap bubble of radius r and surface tension T 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

Work done in forming a soap bubble of radius R is W. Then workdone is forming a soap bubble of radius '2R' will be :

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