A magnetic field has a magnitude of 1.20 x 10-3 T, and an electric field has a magnitude of 5.20 103 N/C. Both fields point in the same direction. A positive 1.8 µC charge moves at a speed of 2.60 x 106 m/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on the charge.
