A charged particle (mass = M, charge = Q > 0) moves in a region of space where the magnetic field has a constant magnitude of B and a downward direction. What is the magnetic force on the particle at an instant when it is moving horizontally toward the north with a speed V?
 a. QVB toward the east
  b. Zero
  c. QVB toward the west
  d. QVB upward
  e. QVB toward the south

Question 2

You stand near the earth's equator. A positively charged particle that starts moving parallel to the surface of the earth in a straight line directed east is initially deflected upwards. If you know there are no electric fields in the vicinity, a possible reason why the particle does not initially acquire a downward component of velocity is because near the equator the magnetic field lines of the earth are directed
 a. upward. b. downward. c. from south to north.
  d. from north to south.
  e. from east to west.
