A proton traveling horizontally due east enters a region that contains both a uniform magnetic field and a uniform electric field. (We are ignoring the earth's magnetic field and assuming that the uniform magnetic field is provided by a strong magnet.) The electric field lines point horizontally due north. It is observed that the proton continues to travel in a straight line toward the east. a) What direction is the electric force on the proton? Explain. b) What direction is the magnetic force on the proton? Explain. c) In what direction must the magnetic field lines point? Explain.
