Homework Help: Lorentz Force

  1. Apr 18, 2006 #1
    In the attached figure (also at http://img215.imageshack.us/img215/3231/lorentz5sa.png" [Broken]) is a positively charged particle entering a magnetic field that points out of the page. The velocity of the particle is in the upward direction, orthogonal to the magnetic field.

    My only question is, based on the equation [itex]\vec{F}=Q\vec{v}\times\vec{B}[/itex], am I correct to say that the force due to the magnetic field is horizontally to the right?

    Thank you.

    yes you can say that by using the left hand rule.

    I am not sure if that was a typo or a joke, so just in case...
    Amcavoy is correct by the standard convention which is the right hand rule.
