Homework Statement:
 In polar coordinates find the force as a function of radial coordinate F(r) that allows a particle to move in logarithmic spiral orbit r=k*e^(α*θ) , where k and a are constants.
Relevant Equations:
 ## \frac{d^2}{dθ^2}(1/r)+1/r=(μr^2)⋅F(r)/l^2 ##
I believe I solved this. Is this solution true? Can please anyone just check?
