Hall effect data in an actual student laboratory was as follows: for a doped indium arsenide strip of thickness 0.15 mm, with a current of 100 mA flowing through the strip and a magnetic field of 50 mT perpendicular to the strip, the measured Hall voltage was 11.5 mV. (a) Use these data to find the density of charge carriers. (b) Find the density of charge carriers using the complete data set shown in the accompanying table.
