Solve the given question:
Question: A 6.60 µC particle moves through a region of space where an electric field of magnitude 1200N/C points in the positive x direction and a magnetic field of magnitude 1.03T points in the positive z direction.
Part A: If the net force acting on the particle is 6.25 x 103 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.
I need help to solve the above question and give your answers numerically separated by commas.
