Magnetic Field and E Fields

  1. Apr 11, 2007 #1
    1. An electron has an initial velocity of (11.0 j + 16.0 k) km/s and a constant acceleration of (2.00 1012 m/s2) i in a region in which uniform electric and magnetic fields are present. If B = (400 µT) i, find the electric field E.
    i. j. k


    2. F=ma
    F=qv cross B



    3. I tried finding F through one of the ways listed above, and tried using F=Eq equation to get E. However, i got different values for the force and cannot seem to get the answer.
