Consider the tension in a differential portion due to the surface tension Td(theta) which would be equal to 2*pi.rd(theta)
And then apply the formula for young's modulus.
what exactly is alpha and why is it 2?
That is a 2 written badly. 😅 Because of the 2 layers of soap solution tension is 2T.l
Oh alright xD
thats what i thought as well intially but thought that i somehow went wrong
