Question
A Soap bubble of radius R is surrourded by another soap bubble of radius 2R, as shown. Take surfacetension = S. Then, the pressure inside the smaller soap bubble, in excess of the atmospheric pressurewill be
Solution
The pressure inside a soap bubble is given by the formula P = 4S/R, where S is the surface tension and R is the radius of the bubble.
In this case, the radius of the smaller bubble is R, so the pressure inside the smaller bubble, in excess of the atmospheric pressure, will be P = 4S/R.
