Doubleslit experiment and heisenberg uncertainty

[Swatje]

Hello there!I have a small question regarding Heisenberg uncertainty relationship. If one sets up a double slit experiment and one looks through which hole the electron passes, so it acts as a particle and you know exactly where it is. If immediately after that slit, you place some sort of magnet, or other application to measure the speed, how will your result be inaccurate?Greetings,

What are your thoughts? What does one have to do to know which slit the particle went through? Is this a homework question?

Nah, a coursework question. But I understand it now, case closed ;).
