(III) A long copper strip wide and
thick is placed in a 1.2-T magnetic field as in Fig. 20-21a. When a steady current of 15 A passes through it, the Hall emf is measured to be \(1.02 \mu V\). Determine
the drift velocity of the electrons and
the density of free (conducting) electrons (number per unit volume) in the copper. [Hint: See also Section
