"A 6.50 −μC particle moves through a region of space where an electric field of magnitude 1450 N/C points in the positive x direction, and a magnetic field of magnitude 1.24 T points in the positive z direction. Part A If the net force acting on the particle is 6.25×10−3 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."
