When a particle of charge q > 0 moves with a velocity of U1 at 45.0o from the +x-axis in the xy-plane a uniform magnetic field exerts a force F, along the -z-axis (Fig). When the same particle moves with a velocity U2 with the same magnitude as u1 but along the +z-axis, a force u2 of magnitude F2 is exerted on it along the +x-axis.
(a) What are the magnitude (in terms of q, u1 and F2) and direction of the magnetic field?
(b) What is the magnitude of F1 in terms of F2?
