Homework Help: Uncertainty Principle and angular position

  1. Nov 25, 2008 #1
    Verify that the uncertainty principle can be expressed in the form [PLAIN]http://www.colorado.edu/physics/phys2170/phys2170_spring96/hws/2170_hw73.gif,[/URL] [Broken] where [PLAIN]http://www.colorado.edu/physics/phys2170/phys2170_spring96/hws/2170_hw74.gifis[/URL] [Broken] the uncertainty in the angular momentum of a particle, and http://www.colorado.edu/physics/phys2170/phys2170_spring96/hws/2170_hw75.gif is the uncertainty in its angular position. (You may think of a particle, mass m, moving in a circle of fixed radius r, with speed v)

    b) At what uncertainty in L will the angular position of a particle become completely indeterminate?
