							according to me value of coefficent of friction and radius is needed in the questionlet coeffiecent of friction be $\mu$Vmax=$\sqrt{\frac{Rg(\tan\Theta +\mu )}{1-\mu \tan\Theta }}$  where R=radius  g=accleration due to gravity(=9.8)  $\Theta$=30 degress  Vmin=$\sqrt{\frac{Rg(\tan\Theta -\mu )}{1+\mu \tan\Theta }}$   hence  you can find the ratio derivation of Vmax and Vmin is a topic for another day so i am not discussing it right now if you want to know it then ask
