German physicist Werner Heisenberg related the uncertainty of an object's position (Îx) to the uncertainty in it's velocity Îv.
Îx ⥠h/4ÏmÎv where h is Planck's constant and m is the mass of the object.
The mass of an electron is 9.11 x 10-31kg.
What is the uncertainty in the position of an electron moving at 3.00 x 106 m/s with an uncertainty of Îv =0.01x106 m/s?
