Figure shows a portion of a silver ribbon with z 1 = 11.8 mm and y =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. If there are 5.85 x 10²* 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 voltage. Let the Figure represents a strip of an unknown metal of the same dimensions as those of the silver ribbon. When the magnetic field is 2.29 T and the current is 78.0 A, the Hall voltage is found to be 131 µV. Find the density of free electrons in the unknown metal?
