Question

Pretend you tip the apparatus up at an angle so that the face of the Helmholtz coil is parallel to the direction of the earth's magnetic dip angle. (By "face of the Helmholtz coil" we mean the Area Vector is parallel to Earth's Magnetic Field Vector.) The controls are now pointed up into the air. What would the effect be on the beam of electrons? (Assume you have not changed V or I.) Select one: a. The diameter would stay the same. b. The diameter would be half as big. c. The diameter would increase. d. There is not enough information to know the effect. e. The diameter would be twice as big. f. The diameter would decrease.
