    1. The problem statement, all variables and given/known data

    An electron is confined within a region of atomic dimensions on the order to 10-10 m. Compute the uncertainty in its momentum.

    2. Relevant equations


    3. The attempt at a solution

    I know this problem involves a simple application of Heisenberg's uncertainty principle; however, I'm having a hard time deciding what I should use as my uncertainty in the position of the particle. Could someone help me reason this out?
