A horizontal current-carrying wire that is perpendicular to the plane of the paper is placed in a uniform magnetic field of magnitude 2.2 mT that is parallel to the plane of the paper and points down. At the distance 1.0 cm to the right of the wire, the total magnetic field is zero. What physical quantity can you determine using this information?a. the current in the wireb. the potential difference at the ends of the wirec. the resistance of the wired. the length of the wire
