Th
But how can i apply the condition of fixed volume
If i make the area of circle as function of angle bw the bubbles then
Where can i apply condition of fixed air moles
Do i Missing something
Ohhh
The bubbles are identical so the force at a point will have same magnitudes but they have different direction , but Fnet = 0 so these three force vector must sum to zero only possible when they are at 120° hence Force net = 0 means potential energy = minimum hence area of circular film will...
They will share a common flat surface where force on both sides is equal and we also don't have any other information so how we start
Otherwise thanks for replying
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
I tried to use
Energy = Surface tension * area
And then...
