The concentration of free electrons in silver is 5.85 × 1028 per m3. A strip of silver of thickness 0.050 mm and width 20.0 mm is placed in a magnetic field of 0.80 T. A current of 10.0 A is sent down the strip.

(a) What is the drift velocity of the electrons?
(b) What is the Hall voltage measured by the meter?
(c) Which side of the voltmeter is at the higher potential?
