Problem 9CQ
A capacitor with plates separated by distance d is charged to a potential difference . All wires and batteries are disconnected, then the two plates are pulled apart (with insulated handles) to a new separation of distance 2 d .
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 change as the separation increases? If so, by what factor? If not, why not?
