Compare the trajectories
Particles of charge +3Q and -2Q have the same mass.
They enter a region of constant field with constant velocity in the +x direction
1, 2, 3, 4, and 5 are possible trajectories.
  1. Path 1 for +3Q and Path 4 for -2Q
  2. Path 4 for +3Q and Path 1 for -2Q
  3. Path 3 for +3Q and Path 3 for -2Q
  4. Path 2 for +3Q and Path 5 for -2Q
  5. Path 5 for +3Q and Path 2 for -2Q
