Asymmetrical charged parallel plates capacitor

[abdo799]

If i have a parallel plates capacitor , where the plates have different charges , eg, one plate has 1 C of charge and the other is neutral , what's the potential difference? what if i grounded the neutral plate , will it gain 1 C of charge?

What normally happens when a charged conductor is brought close to an uncharged conductor... and then you Earth the uncharged conductor?

yea, just like charging by induction , but about the charge i use to find out the V using CV=Q , should i use the mean of the sum of the absolute values of both charges?

There's a fairly decent description here:

If you sketch out the situation - careful to draw the plates as having a thickness - you should see how to deal with it.
The "top" plate has a single row of +++++ across the lower surface, there's a gap, and the bottom plate has a row of ------- (minuses) along the top and ++++++ along the bottom. What does that look like to you?

If you ground the bottom plate, you get rid of the ++++ on the bottom.
