Homework Statement
Determine the work required to move the plates of an ideal parallel plate capacitor from a separation distance of D to an integer multiple of D, (assume only one moves for simplicity). The each plate has an area A.
Homework Equations
F = q^2 /( 2 e_0 A) field strength between the plates
[tex]\Delta[/tex] V = U/q
[tex]\Delta[/tex]U = -W
[tex]\Delta[/tex]V= Qd/e_0 A
The Attempt at a Solution
moving the terms above around I came up with U = Qdq/e_0A
I know I need an integral here, probably evaluated between D and multiple of D(its a general solution that's needed)
Am I on the right track?
