As a space shuttle moves through the dilute ionized gas of Earth’s ionosphere, the shuttle’s potential is typically changed by -1.0 V during one revolution. Assuming the shuttle is a sphere of radius 10 m, estimate the amount of charge it collects.
In a photocell, ultraviolet (UV) light provides enough
energy to some electrons in barium metal to eject them
from the surface at high speed. To measure the maximum
energy of the electrons, another plate above the barium
surface is kept at a negative enough potential that the emitted
electrons are slowed down and stopped, and return to the
barium surface. See Fig. 17-46. If the plate voltage is –3.02 V
(compared to the barium) when the fastest electrons are
stopped, what was the speed of these electrons when they
were emitted?

With the dial set at 180° (corresponding to C — 800 pF), the capacitor is connected to a 500-V source. After charging, the capacitor is disconnected from the source, and the dial is turned to 0°.

This effectively makes the cell wall a charged capacitor. Because a cell's diameter is much larger than the wall thickness, it is reasonable to ignore the curvature of the cell and think of it as a parallel- plate capacitor.
