A strip of copper 150 mm thick and 4.5 mm wide is placed in a uniform magnetic field of magnitude 0.65 T, with perpendicular to the strip. A current i = 23 A is then sent through the strip such that a Hall potential difference V appears across the width of the strip. Calculate V. (The number of charge carriers per unit volume for copper is 8.47* 10^28 electrons/m3.)
