Homework Help: Heisenberg uncertainty

  1. Jul 30, 2010 #1
    1. The problem statement, all variables and given/known data
    hi i am new to this principle if i was to calculate the Heisenberg uncertainty of a nuclei of radius r would i take my delta x as r or as the diameter of the nuclei

    thanks
    2. Relevant equations



    3. The attempt at a solution

    The Heisenberg principle tells us that the product of the uncertainties of position and momentum must be greater than a certain number.

    You would take your delta x as your uncertainty in the measurement (i.e. the radius of your nuclei plus or minus delta x).
