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 down towards the table. what would the effect be on the beam of electrons? (assume you have not changed v or i.)a.) the diameter would stay the same. b.) the diameter would decrease. c.) the diameter would increase. d.) there is not enough information to know the effect. e.) the diameter would be half as big. f.) the diameter would be twice as big.
