Quizplus · Accepted Answer

The Heisenberg uncertainty principle states that the uncertainty in the position of a particle is inversely proportional to the uncertainty in its momentum. In this case, the uncertainty in the speed of the electron is 3.5 × 10³ m/s, so the uncertainty in its position is at least 1.7 × 10^-8 m.

According to the Heisenberg Uncertainty Principle, If the Uncertainty in the Speed
