Homework Help: Uncertainty Principle

  1. Nov 25, 2008 #1
    Verify that the uncertainty principle can be expressed in the form 2170_hw73.gif , where 2170_hw74.gif is the uncertainty in the angular momentum of a particle, and 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?

    What have you tried? You need to show some sort of attempt to get assistance here as per forum policy.

    Once you have answered part (b), you will see that the relation that you're supposed to prove in part (a) cannot be quite correct!
