A small particle with positive charge $q=+3\mathrm{.}75{10}^{-4}C$ and mass $m=6\mathrm{.}00{10}^{-5}kg$ is moving in a region of uniform electric and magnetic fields. The magnetic field is $B=4\mathrm{.}00T$ in the $+z-$direction. The electric field is also in the $+z-$direction and has magnitude $E=55\mathrm{.}0\frac{N}{C}.$ At time $t=0$ the particle is on the $y-$axis at $y=+1\mathrm{.}00m$ and has velocity $v=25\mathrm{.}0\frac{m}{s}$ in the $+x-$direction. Neglect gravity.
