A particle is constrained to move (without friction) on acircularwire rotating with constant angular speed Ï about averticaldiameter. Find the equilibrium position of the particle,andcalculate the frequency of small oscillations aroundthisposition. Find and interpret physically a criticalangularvelocity Ï=Ïc that divides the particle'smotioninto two distinct types. Construct phase diagrams forthe two casesÏ<Ïc andÏ>Ïc.
