Remember, that for any parallel plate capacitor V is not affected by distance, because: V = W/q (work done per unit charge in bringing it from on plate to the other) and W = F x d. and F = q x E. so, V = F x d /q = q x E x d/q.

6 FAQs about [The capacitor plates are grounded after charging]
What happens if a capacitor is connected to a ground?
In open circuit, no charge flows. If we connect both the capacitor plates it makes closed circuit, charge flows in the circuit, as a result charges on the plates neutralizes to zero. If only +ve plate of the capacitor is only connected to ground there is no closed circuit. no charges flows from the ground.
Why does a capacitor have no charges?
After making contact, the plate in contact with the Earth then has the same potential as the Earth. But no charges flow because there's not a complete circuit, and because the charges on either plate are attracting each other and holding them to the inside plate surfaces. The capacitor is still a net neutral object (as it the Earth).
Does a capacitor have a charge?
No. The total charge of the capacitor is always the same. You've just moved some of the charge from one plate to the other. The word "charge" in this case just means "to fill up with energy", just like you can "charge" an inductor with current or "charge" a scuba tank with air or "charge" a cannon with gunpowder. It's an unfortunate terminology.
How do you charge a capacitor?
You're charging a capacitor made up of the Earth as one plate, and the ball as the other. The capacitance of this capacitor is very small, because the "plates" are so far apart, so to move any noticeable charge, you need to use thousands of volts. For flow of charge, the circuit should be closed. In open circuit, no charge flows.
Will a capacitor discharge if plugged into a ground?
From this we may see that earth (ground+atmosphere) is a capacitor itself. It was experimentally checked that the ground has negative charge and so it is the source of electrons. So in your question you plug one capacitor to the half of the other one with huge charge. The answer is - no it will NOT discharge COMPLETELY.
What happens if you charge a capacitor using a battery?
When we charge a capacitor using a battery and then remove the battery, the plates of capacitor becomes charged. One holds positive charge and the other one gets equal negative charge. o. k. ? Now if we attach a wire to the positive plate and connect it to the ground , will the electrons from ground climb on the positive plate and make it neutral ?
