Help Needed: Finding Components of Particle Velocity

[Johnson]

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?

Hi Johnson!

Hint: Use the Lorentz force: F = q(E + v x B)
