Textbook Question
Chapter 25, Problem 7CQ
A capacitor with plates separated by distance d is charged to a
potential difference
then the two plates are pulled apart (with insulated handles) to a
new separation of distance 2d.
a. Does the capacitor charge Q change as the separation increases?
If so, by what factor? If not, why not?
b. Does the electric field strength E change as the separation
increases? If so, by what factor? If not, why not?
c. Does the potential difference
increases? If so, by what factor? If not, why not?
