A 6.70 -uC particle moves through a region of space where an electric field of magnitude 1300 N/C points in the positive x direction, and a magnetic field of magnitude 1.02T points in the positive z direction. If the net force acting on the particle is 6.24×10^?3 in the positive x direction, find the components of the particle's velocity. Assume the particle's velocity is in the x-y plane. Enter your answers numerically separated by commas.
