An experiment is performed to demonstrate the Hall effect. A thin rectangular strip of conducting material with width 15 cm and length 31 cm is attached to a battery and immersed in a 2.60 T field perpendicular to its surface. This produced a Hall voltage of 14 μV. (Assume the battery is connected to the shorter sides of the thin rectangular strip.) Suppose that the cross-sectional area of the strip (the area of the face perpendicular to the electric current) is 1 mm² and the current is independently measured to be 3 mA. What is the number density of the charge carriers? carriers/m³
