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 electric field [tex]_{}Bo[/tex], parallel to the z axis is provided, and the beam is made to rotate with a constant, uniform angular velocity = w
A: Use Gauss' Law to find the radial electric field in the beam on a cylinder of radius = r<R
I figured out this one and got E = pr/2[tex]\epsilon[/tex]
Sorry about the coding, I'm very new to this. Well that is supposed to be epsilon, and it should not be a power.
I could not figure out B or C though.
B: Find the azimuthal (tangential) velocity of a particle in the beam at r<R
C: Find the total (electric and magnetic) force required on a particle at r<R
D: Set force in "C" equal to the centripetal force required to keep a particle on a circular path of radius = r<R
