Chapter 4: Q5E (page 948)
A -4.80@mC charge is moving at a constant speed of 6.80 * 105 m>s in the +x-direction relative to a reference frame. At the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points:
(a) x= 0.500 m, y= 0, z= 0;
(b) x= 0, y= 0.500 m, z= 0;
(c) x= 0.500 m, y= 0.500 m, z= 0;
(d) x= 0, y= 0, z= 0.500 m?
