In a Hall-effect experiment, a current of 3.0 A sent lengthwise through a conductor 0.83 cm wide, 3.0 cm long, and 9.3 μm thick produces a transverse (across the width) Hall potential difference of 9.7 μV when a magnetic field of 1.5 T is passed perpendicularly through the thickness of the conductor. From these data, find (a) the drift speed of the charge carriers and (b) the number density of charge carriers. (a) Number i (b) Number Mi ! ! Units Units m/s m^-3 or 1/m^3
