Determine the work required to move the plates of an ideal parallel plate capacitor from a seperation distance of D to an integer multiple of D, (assume only one moves for simplicity). The each plate has an area A.

2. Relevant 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

3. 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 thats needed)

Am I on the right track?
