Finding the speed of a proton in a mass spectrometer

  1. Dec 31, 2012 #1
    1. The problem statement, all variables and given/known data
    A mass spectrometer uses either a magnetic field or an electric field to deflect charged particles.

    A proton starts from rest a plate P. The Speed of the proton as it passes through the hole in plate Q is?

    V= 10000 V
    Mass of a proton = 1.67x10^-27
    Charge of a proton = 1.6x10^-19

    With this you then need to find the magnetic field intensity.

    Radius of curvature of a protons path is 3.00 m.

    2. Relevant equations

    I have no clue?

    3. The attempt at a solution

    Dont know were to start?
