Problem 27.7: Rank charges as they move through magnetic field

Please wait for the animation to completely load.

Six objects (all with a mass of 5 grams) are shot into a region of constant magnetic field. The blue object has a charge of 6 mC. The position and velocity of the blue object are given in the table (position is given in centimeters and time is given in seconds). All objects are located at x = - 50 cm at time t = 0 s. Restart.

  1. Rank the objects based on their velocity when they first encounter the magnetic field, from lowest to highest.
  2. How does the magnitude of the velocity of each object change as it interacts with the magnetic field?
  3. Rank the objects based on their charge, from lowest to highest.
  4. What are the direction and magnitude of the magnetic field?
