An extrinsic semiconductor shown in figure carries a current of 2 mA along its length parallel to +x axis.
When the majority charge carrier concentration is
and the sample is exposed to a constant magnetic field applied along the +z direction, a Hall voltage of 20 mV is measured with the negative polarity at
plane. Take the electric charge as
