A magnetic field has a magnitude of 0.0011 T, and an electric field has a magnitude of 4.9 × 103 N/C. Both fields point in the same direction. A positive 2.6-μC charge moves at a speed of 2.9 × 10° m/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on the charge. 1441 Number i ! Units N Sketch the situation and include arrows that represent the direction of the E and B fields as well as an arrow that represents the velocity of the charge. The electric force on the charge is in the same direction as the electric field and its magnitude is given by equation 18.2. Use Right-Hand Rule No.1 to determine the direction of the magnetic force on the particle, whose magnitude is given by equation 21.1. If the magnetic and electric forces are in the same direction, they add as scalars. If they are perpendicular, then you'll need to use the Pythagorean theorem.
