A singly charged ion all together passes via a magnetic field, B and an electric field, E, both oriented at right angles to one other. The ion path in turn is perpendicular to each of the fields which are of just the proper strength and direction to precisely cancel each other. Therefore there are no unbalanced forces acting on the ion. When E = 5.0 x 10^5 N/C and B = 2.5T, determine the ion speed (in 10^5 m/s)?
