One component of a magnetic field has a magnitude of 0.074 T and points along the +x axis, while the other component has a magnitude of 0.020 T and points along the -y axis. A particle carrying a charge of +7.50 10-5 C is moving along the +z axis at a speed of 3.20 103 m/s. (a) What is the magnitude of the net magnetic force that acts on the particle? (b) What is the angle that the net force makes with respect to the +x axis? I figured out the first question using F=Bqvsin90 for X anf Y and then used pythag. to get the answer which was 0.018397 N. I am having problems with (b). I don't know how to find the angle because it is not on a plane I think. The net force has XYZ components and I don't know how to find an angle for that. Could you please help? Thanks!!
