If a section of soap bubble (of radius R) through its centre is considered then force on one half due to surface thension is

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

Air is pushed into a soap bubble of radius R to triple its radius. If the surface tension of the soap solution is S, then find out an expression for the work done in this process.

Air is pushed inot a soap bubble of radius r to duble its radius. If the surface tension of the soap solution is S, the work done in the process is

Air is pushed into a soap bubble of radius r to double its radius. If the surface tension of the soap solution is S, the work done in the process is

Air is pushed into a soap bubble of radius r to double its radius, of the surface tension of the soap solution is S, the work done in process is

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

A soap bubble of radius r si blown up to form of bubble of radius 3r under isothermal conditions . What is the energy spent in doing so if the surface tension of soap solution is S.
