A long, straight wire lies along the $x-$axis and carries current $I=65\mathrm{.}0A$ in the $+x-$direction. A small particle with mass $3\mathrm{.}00{10}^{-6}kg$ and charge $8\mathrm{.}00{10}^{-3}C$ is traveling in the vicinity of the wire. At an instant when the particle is on the $y-$axis at $y=8\mathrm{.}00cm,$ its acceleration has components $a_x=-5\mathrm{.}00{10}^3\frac{m}{s^2}$ and $a_y=+9\mathrm{.}00{10}^3\frac{m}{s^2}.$
