One component of a magnetic field has a magnitude of 0.0406 T and points along the +x axis, while the other component has a magnitude of 0.0725 T and points along the -y axis. A particle carrying a charge of +1.83E-5 C is moving along the +z axis at a speed of 4.78E3 m/s.
a) Find the magnitude of the net magnetic force that acts on the particle.
b) Determine the angle that the net force makes with regard to the +x axis.
