A 0.263 kg ball, containing a net charge of -159.35 mC, is thrown horizontally into a region of uniform magnetic field of field strength 10 Tesla. The ball is traveling perpendicular to the B-field at the instant it is thrown, and at that moment, it is known to be traveling at v=20 km/s. Say, the B-field is applied *into the plane of the paper/screen. How far (in meters) will the ball deflect from its initial horizontal path, due to the action of the B-field along, after it has traveled D=2491 meters horizontally while being deflected along its path. NOTE: if you end up getting 2 possible correct answers, enter the value that is LESS than "D". Both answers, however, are correct. It will be worthwhile to think about the meaning of the solution that is MORE than "D" Deflection (say, y) = 1
