Review Answer Key: Right-Hand Rules 1. In the sketch to the right, which path (A or B) represents the path that would be followed by a positively-charged particle entering the region of magnetic field with initial velocity vector as shown? Use a right-hand rule to help explain your answer A B 2. In the sketch to the left, draw the path that would be followed by a negatively-charged particle entering the region of magnetic field with initial velocity vector as shown. Use a right-hand rule to help explain your answer 3. In the sketch to the right, a particle moves in a circular path in a magnetic field region. a) Sketch the direction of the force vectors at the points labeled “A”, “B”, and “C” C A b) Which direction is the does the magnetic field point if the particle is positively-charged? c) Which direction would the magnetic field point if the particle is negatively-charged? 4.
