An accelerating voltage of 2.65 multiply.gif 103 V is applied to an electron gun, producing a beam of electrons originally traveling horizontally north in vacuum toward the center of a viewing screen 33.8 cm away.
(a) What is the magnitude of the deflection on the screen caused by the Earth's gravitational field?
(b) What is the magnitude of the deflection on the screen caused by the vertical component of the Earth's magnetic field, taken as 20.0 µT down?
