how can we know that the position of electron?
Answers
Answer:
example, you can measure the position of a moving electron by scattering light or other electrons from it. Those probes have momentum themselves, and by scattering from the electron, they change its momentum in a manner that loses information.
Explanation:
There are many reasons for tracking electrons:
If there is a magnetic field, and a moving electron is deflected, then the final "position" lets us calculate the strength of the magnetic field.
If a proton is available, then the "position" of the electron determines whether it will be captured to form hydrogen molecule or not.
Static Electricity is due to electrons, so knowing the "position" of the electrons tell us the strength of the attractive forces.
Current Electricity is due to the flow of electrons, so knowing the "position" of the billions of electrons tells us how much current is flowing.
For particle detectors (Large Hadron Collider) the "position" of the detected electron indicates which particle has been found.
