Connecting a conductor with a voltage source

[fawk3s]

This kind of confuses me. You have a capacitor which has a voltage of 200 volts. Now when doubling the distance between the plates and adding a 100 V voltage source to it, it is said that the voltage between the capacitor plates stays the same, as in 200 V.
I don't follow. Someone care to explain?

Thanks in advance,

Where is it said such a thing?

It was in a physics problem concerning conductors. But I just found out that its because the voltage source works against the work done when moving the plates. A current is created and the extra voltage created does the work. So the voltage between the plates should stay the same to a certain point.
