A strip of copper 220 um thick and 4.70 mm wide is placed in a uniform magnetic field of magnitude B = 0.96 T, that is perpendicular to the strip. A currenti- 25 Ais then sent through the strip such that a Hall potential difference Vappears across the width. Calculate V. (The number of charge carriers per unit volume for copper is 8.47 x 10 electrons/m*) Number Units
