Homework Help: New type of mass spectrometer

  1. Jan 25, 2010 #1
    Hi i've attached the circuit as a word document, along with the question. I was not sure about the answers given, which I have copied below:

    Between plates field is uniform
    Acceleration is constant
    Energy gained = 2000e where does 2000 come from, isnt it 4?
    All ions have same F or same energy
    From hole to detector is zero field/force
    Ion travels at constant speed
    g negligible - why?
    time proportional to 1 /velocity how?
    time proportional to 1 /mass how?
    in a vacuum there are no collisions or friction forces
