13.An electron moves in the negative x direction, through a uniform magnetic field in the negative y direction. The magnetic force on the electron is: TV Tag A) in the negative x direction B) in the positive y direction C) in the negative y direction D) in the positive z direction E) in the negative z direction 14. An electron is moving north in a region where the magnetic field is south. The magnetic force exerted on the electron is: A) zero B) up 15. C) down D) east E) west A hydrogen atom that has lost its electron is moving east in a region where the magnetic field is directed from south to north. It will be deflected: A) up B) down C) north D) south E) not at all 16. A beam of electrons is sent horizontally down the axis of a tube to strike a fluorescent screen at the end of the tube. On the way, the electrons encounter a magnetic field directed vertically downward. The spot on the screen will therefore be deflected: A) upward B) downward C) to the right as seen from the electron source D) to the left as seen from the electron source E) not at all
