The Hall effect was used to find the density of charge carriers in a rectangular sample of an unknown material with length 2.2 cm, width 1.5 cm, and height 0.30 cm. A Hall voltage of 57 µV for a 3.4 A current along the length of the sample was observed in a 3.8 T magnitude magnetic field perpendicular to the current. Determine the density of the charge carriers in the sample.
