Calculate the value of critical free energy if the value of (ΔGs (misfit strain)-ΔGv) is given as 22/7? (γ represents the surface free energy?

Calculate the value of critical free energy if the value of (ΔGs (misfit strain)-ΔGv) is given as 22/7? (γ represents the surface free energy? Correct Answer (16/3) γ3

When we differentiate the equation related to the total free energy with respect to free energy we end up with the equation G* = (16/3)πγ3/ (ΔGs- ΔGv)2, substituting the respective values in the equation will end up giving the result as (16/3) γ3.
