What will be the area of common surface of two identical bubbles of radius R , i know there common surface will be flat as the radius of curvature of comman surface will tends to Infinity , but how do i relate with area of flat surface(adsbygoogle = window.adsbygoogle || []).push({});

I tried to use

Energy = Surface tension * area

And then energy conservation

But failed

Any help will be appreciated
