A metal bar of length moves with a velocity v parallel to an infinitely long straight wire carrying a current I as shown in the figure. If the nearest end of the perpendicular bar always remains at a distance 2 from the current carrying wire, the potential difference (in volt) between two ends of the moving bar is
