One component of a magnetic field has a magnitude of 0.048 T and points along the +x axis, while the other component has a magnitude of 0.065 T and points along the -y axis. A particle carrying a charge of +2.0 × 10-5 C is moving along the +z axis at a speed of 4.2 × 103 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 respect to the 1x axis.
