Question

What does the Heisenberg uncertainty principle state?It is impossible to know either the position or the velocity of an electron.It is impossible to know both the position and velocity of an electron at the same time.It is impossible to know the mass of an electron.

Answer 1

The Heisenberg uncertainty principle states that the exact position and momentum of an electron cannot be simultaneously determined. This is because electrons simply don't have a definite position, and direction of motion, at the same time.

From the options given, the correct one would be:

"It is impossible to know both the position and velocity of an electron at the same time."
