A $6\mathrm{.}60-C$ particle moves through a region of space where an electric field of magnitude $1500\frac{N}{C}$ points in the positive $x$ direction, and a magnetic field of magnitude $1\mathrm{.}22$ T points in the positive $z$ direction.

Part A

If the net force acting on the particle is $6\mathrm{.}25{10}^{-3}N$ in the positive $x$ direction, find the compo of the particle's velocity. Assume the particle's velocity is in the $x-y$ plane.
