Question
Two10 cm-diameter electrodes 0. 50 cm apart form a
parallel plate capacitor. The electrodes are attached by metal
wires to
the terminals of a 15V battery. After a long time, the capacitor
is disconnected from the battery but is not discharged. What
are the charge on each electrode, the electric field strength
inside the capacitor, and the potential difference between the
electrodes
a. Right after the battery is disconnected?
b. After insulating handles are used to pull the electrodes away
from each other until they are 1.0 cm apart?
c. After the original electrodes (not the modified electrodes of
part b) are expanded until they are 20 cm in diameter?
