How does the uncertainty principle relate the accuracy of knowing the position of an electron to its velocity?

Options

  1. AIf the position is known accurately, the velocity is also known accurately.
  2. BIf the position is known accurately, the velocity is uncertain.
  3. CIf the velocity is known accurately, the position is uncertain.
  4. DThere is no relationship between position and velocity uncertainty.

Correct answer

C. If the velocity is known accurately, the position is uncertain.

Step-by-step solution

If the velocity of the electron is known precisely (∆(vx) is small), then the position of the electron will be uncertain (∆x will be large).
