• Energy

Which of the following violates the uncertainty principle?

• Determining the exact position of an electron
• Measuring both position and momentum simultaneously with absolute precision
• Measuring time and energy for a photon

What does the uncertainty principle imply about the state of an electron?

• The electron has a definite position and momentum.
• The electron’s position or momentum cannot be determined accurately at the same time.
• The electron’s mass is uncertain.
• The electron cannot exist outside the nucleus.
