A particle has a charge of q = +4.5 µC and is located at the origin. As the drawing shows, an electric field of Ex = +249 N/C exists along the +x axis. A magnetic field also exists, and its x and y components are By = +1.9 T and By = +1.2 T. Calculate the force (magnitude and direction) exerted on the particle by each of the three fields when it is (a) stationary, (b) moving along the +x axis at a speed of 345 m/s, and (c) moving along the +z axis at a speed of 345 m/s.
