Homework Help: Applying the Motor Principle

  1. Jan 16, 2008 #1
    A charged particle with a charge-to-mass ratio of 5.7x10^8 C/Kg travels in a magnetic field of strength 0.75T in a circular path that's perpendicular to the magnetic field. What is the period of revolution for this particle.

    The magnetic force exerted provides the centripetal force required to keep it in a circular path.
    Do you know an equation for the magnetic force exerted on a charge,Q,moving with a velocity,v, in a magnetic field of flux density,B?
    Do you know an equation for centripetal force??
