We observe that a moving charged particle experiences no magnetic force. From this we can definitely conclude that
 
  A) no magnetic field exists in that region of space.
  B) the particle must be moving parallel to the magnetic field.
  C) the particle is moving at right angles to the magnetic field.
  D) either no magnetic field exists or the particle is moving parallel to the field.
  E) either no magnetic field exists or the particle is moving perpendicular to the field.

Question 2

Two in-phase loudspeakers are 3.0 m apart. They emit sound with a frequency of 490 Hz.
 
  A microphone is placed half-way between the speakers and then moved along the line joining the two speakers until the first point of constructive interference is found. At what distance from that midpoint is that first point? The speed of sound in air is 343 m/s. A) 0.18 m
  B) 0.35 m
  C) 0.50 m
  D) 0.70 m
  E) There is no point in that line where constructive interference occurs.
