You are observing the motion of a particle of charge 2.8 nC, travelling in a uniform magnetic field of unknown magnitude and direction. By analysing the motion of the charge, you determine that

  • When the particle is travelling at a speed of 6.8 m/s in the +, direction, it experiences a force of 5.44 mN in the +0 direction;

  • When later it is observed to be moving in the +z direction at 3.2 m/s, the force it experiences is still in the +y direction but is smaller in magnitude by 1. 6 mN.

    Determine the magnitude and direction (plane and angle in that plane) of the magnetic field in which the particle is moving.
