1. The problem statement, all variables and given/known data The speed of an electron is measured to within an uncertainty of 2e4 m/s. What is the size of the smallest region of space in which the electron can be confined? 2. Relevant equations Diracs Constant=ΔxΔp p=mv 3. The attempt at a solution what I did was (Diracs Constant)/mv = Δx, (1.054560653e-34)/((9.109e-31)(2e4))=6nm this is this incorrect but I dont understand why?
