Homework Help: Electron Path

  1. Jan 23, 2009 #1
    An electron (mass=m, charge=-e) is projected with speed v upward, in the plane of the page, into a region containing a uniform magnetic field B, that is directed into the plane of the page. Describe the electron's subsequent circular motion.

    I tried using the Right-Hand Rule.

    I said: Clockwise rotation; radius of path = mv/(eB). Is this correct?
