Two electrons, both with speed 5.0 x 10^6 m/s, are shot into a uniform magnetic field B. The first is shot from the origin out along the +x-axis, and it moves in a circle that intersects the +z-axis at z = 16 cm. The second is shot out along the +j-axis, and it moves in a straight line. Find the magnitude and direction of B. |
