An alpha particle ( a doubly ionized helium atom with a mass of 6.64 x 10^-27 kg) is traveling with a velocity v=1x10^6 m/s j, which is perpendicular to the direction of the magnetic field the particle experiences a force F = 2x10^-16N k due to a magnetic field B. (j and k are the unit vectors along the Y-axis and the Z-axis. Determine the magnetic field B.

What direction is the magnetic field above?
