Figure shows a portion of a silver ribbon with z1 = 11.8 mm and y1 = 0.23 mm, carrying a current of 120 A in the +x-direction. The ribbon lies in a uniform magnetic field, in the y-direction, with magnitude 0.95 T. Apply the simplified model of the Hall Effect presented in Section 27.9. If there are 5.85 X 1028 free electrons per cubic meter, find
(a) The magnitude of the drift velocity of the electrons in the x-direction;
(b) The magnitude and direction of the electric field in the z-direction due to the Hall Effect;
(c) The Hall emf.
