Homework Help: Help with Magnetic Interactions

  1. Nov 28, 2007 #1
    Particles having mass=m and charge = Q travel parallel to the z axis, forming a beam of radius = R and uniform charge density = p. To keep the beam focused, an external uniform magnetic field, B, parallel to the z axis is provided, and the beam is made to rotate with a constant, uniform angular velocity = w.

    4. Use Gauss' Law to find the radial electric field in the beam on a cylinder of radius r<R

    6a. Find the tangential velocity of a particle in the beam at r<R

    8b. Find the total (electric and magnetic) force on a particle at r<R
