Two equal spherical bubbles of radius a each coalesce to form a spherical bubble of radius b. If P is the atmospheric pressure, show that the surface tension of the bubble is P(2a^3-b^3)/4(b^2-2a^2).

I am only one,
But still I am one.
I cannot do everything,
But still I can do something;
And because I cannot do everything
I will not refuse to do the something that I can do.
