1. Suppose that you accidentally use your left hand, instead of your right hand to determine the direction of the magnetic force that acts on a positive charge moving in a magnetic field. Can you get the correct answer? Why? a. Yes, because the direction you get will be perpendicular to the correct direction. b. Yes, because the direction you get will be opposite to the correct direction. c. No, because the direction you get will be perpendicular to the correct direction. d. No, because the direction you get will be opposite to the correct direction.

  1. Suppose that you accidentally use your left hand, instead of your right hand to determine the direction of the magnetic force that acts on a positive charge moving in a magnetic field. Can you get the correct answer? Why?
  2. Yes, because the direction you get will be perpendicular to the correct direction.
  3. Yes, because the direction you get will be opposite to the correct direction.
  4. No, because the direction you get will be perpendicular to the correct direction.
  5. No, because the direction you get will be opposite to the correct direction.
  6. Two particles, having the same charge but different velocities, are moving in a constant magnetic field. Between the two particles, which of them experiences the greater magnetic force? If, Particle 1 moves perpendicular to the field, and Particle 2 moves slightly faster than particle 1 at an angle with respect to the field.
  7. Particle 1 experiences the greater force, because it is moving perpendicular to the magnetic field.
  8. Particle 2 experiences the greater force, because it has the greater speed.
  9. Particle 2 experiences the greater force, because a component of its velocity is parallel to the magnetic field.
  10. Both particles experience the same magnetic force, because the component of each velocity that is perpendicular to the magnetic field is the same.
