Deflection due to Magnetic Field

  1. Apr 20, 2012 #1
    1. The problem statement, all variables and given/known data
    The deflection of the electron beam in an old-fashioned tube TV set is accomplished by magnetic forces. Each electron is accelerated through a potential difference of V=30000V. The charge to mass ratio of the electron is 175824175824.176C/kg.

    If there is a x2=0.1m gap between the end of the magnetic field region and the end of the tube, how far from the center of the screen does the beam strike?

    ynet = y1 + y2 =


    2. Relevant equations
    R = mv/qB

    R = (m/eB)*√(2eVacc/m)


    3. The attempt at a solution
    I'm not even sure where to begin. The first thing i'm confused by is what do they mean by end of magnetic field region?

    Im having the same problem as above with the same question.
    it just that the question above seem to be missing a line of information which is
    What magnetic field is required to produce a deflection of y1=0.03m if the magnetic field region is x1=0.065m long?
