german physicist werner heisenberg related the uncertainty of an object's position (δx) to the uncertainty in its velocity (δ????) δx≥ℎ4????mδ???? 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 2.00×106 m/s with an uncertainty of δ????
