A thin metal film of length 2.20 cm, width of 0.550 cm, and thickness of 34.0 micrometers is used to measure the Hall effect. A current of 1.80 A is maintained along the length of the sample. The Hall voltage of 17.0 microVolts is detected across its width, when a magnetic field of 1.50 Tesla is applied normal to the film. 1. Calculate the drift velocity of the charge carriers. 2. Assuming the charge carriers are electrons, calculate their density....
