Homework Help: Mass Spectrometer

  1. Mar 23, 2009 #1
    If I was given that a mass spectrometer was used to separate ions of mass 3.92x10^-25 kg and charge 3.20x10^-19 C from other ions and the ions were accelerated through a potential difference of 80 kV and then sent into a uniform magnetic field, where they were bent in a path of radius 0.60 m and after traveling 180° passed through a slit of width 1.00 mm and height 1.00 cm, where they were collected into a cup:

    Also, the magnetic field, B, is 0.737865 T.

    (a) How would I find the current if the machine was to separate out 80 mg of material per hour?
    (b) How would I calculate the thermal energy produced in the cup in 1 hour?

    Welcome to PF :smile:

    It's best to post homework questions in our homework section:
    Also, we like to see students make an attempt at solving a homework problem before receiving help. If you can tell us what you know, or think may be, towards solving this, we can help steer you along.
