A particle with a charge of q=-1.5C moves at a speed of v=10m/s. It moves through
a region where the magnetic field points directly east and has a magnitude of | vec(B) | = 0.2T.
It experiences a magnetic force of 0.1 N.
a. What is the angle between the velocity and magnetic field vectors?
b. If the force is directed due south, what is the direction of the velocity vector?
