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.
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 ?
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.
But such thing does not happen when we connect positive plate of a charged capacitor to the ground. AFAIK charge doesn't flow (to any significant extent in this context) unless you have a circuit. Connecting one end of a charged capacitor to anything has no significant effect. The explanation about a flow of charge causing D+ to be 0V is spurious.
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.
It is possible to add charge to one plate of a capacitor, but you won't be able to add very much. It's like charging a metal ball. In this case, you're connecting a voltage source between the Earth and the ball, and moving charge from the Earth to the ball. You're charging a capacitor made up of the Earth as one plate, and the ball as the other.
We imagine a capacitor with a charge (+Q) on one plate and (-Q) on the other, and initially the plates are almost, but not quite, touching. There is a force (F) between the plates. Now we …

Because charge can never flow through caps, a capacitor setup in that topology can have a little bit of charge pushed onto the cap before the plates saturate with charge. Once they saturate (or before), you can go ahead and pull that charge …
