A particle with a charge of 34.9 moves with a speed of 68.3 m/s in the positive direction. The magnetic field in this region of space has a component of 0.515 T in the positive direction, and a component of 0.846 T in the positive direction.
a) What is the magnitude of the magnetic force on the particle?
b) What is the direction of the magnetic force on the particle relative to the positive -axis?
