German physicist werner heisenberg related the uncertainty of an object's position (δx) to the uncertainty in its velocity (δv) δx ≥ h/4πmδv where h is planck's constant and m is the mass of the object. the mass of an electron is 9.11×10⁻³¹ kg. what is the uncertainty in the position of an electron moving at 1.00×10⁶ m/s with an uncertainty of δv=0.01×10⁶ m/s? δx ≥
