Determining the radius of curvature mass spectrometre question

  1. Aug 26, 2012 #1
    1. The problem statement, all variables and given/known data
    A mass spectrometer is an important tool in the study of air pollution. However, one of the difficulties faced by scientists is that carbon monoxide molecules (CO), which are major contributors to air pollution, have very nearly the same mass as harmless nitrogen molecules (N2). (CO = 28.0106 u, N2 = 28.0134u). Determine how large a radius of curvature a spectrometer needs to have if these two molecules are to be separated on the photographic plate by at least 0.24mm.


    2. Relevant equations
    r = mv/qB


    3. The attempt at a solution
    ???

    Hello ,
    You also need to include force due to electric field .
    I mean lorentz force
