A+7.00 ? ? c point charge is moving at a constant 9.00×106 m/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 b? it produces at the following points.

enter your answers numerically separated by commas.

bx, by, bz = t

a) x = +0.500m, y = 0, z = 0

b) x = 0,y = -0.500m, z = 0

c) x = 0,y = 0, z = +0.500m

d) x = 0,y = -0.500m, z = +0.500m
