6.60 -micro C particle moves through a region of space where an electric field of magnitude 1200 N/C points in the positive x direction and a magnetic field of magnitude 1.01T points in the positive Z direction if the net force acting on the particle is 6.23 x 10^-3 N in the positive x direction, find the components of the particle's velocity. Assume the particle's velocity is in the x-y plane. Vx = ? Vy = ? Vz = ? I haven't been on here in ages, and I am just stuck on this one question. Thought this would be a perfect time to come back to these forums. I don't even know where to begin...anyone care to help?
