A $+6.00 \mu$ C point charge is moving at a constant $8.00 \times 10^{6} \mathrm{~m} / \mathrm{s}$ in the $+y$ -direction, relative to a reference frame. At the instant when the point charge is at the origin of this reference frame, what is the magnetic-field vector $\overrightarrow{\boldsymbol{B}}$ it produces at the following points:
(a) $x=0.500 \mathrm{~m}, y=0, z=0$
(b) $x=0, y=-0.500 \mathrm{~m}, z=0$
(c) $x=0, \quad y=0, \quad z=+0.500 \mathrm{~m}$
(d) $x=0, \quad y=-0.500 \mathrm{~m}$
$z=+0.500 \mathrm{~m} ?$
