Why does charge flow when a conductor is 'touching' the surface of the earth?
But the potential difference between the two ends of the connecting wire would be distance dependent(?).
As in the figure the potential at $A$ would be potential due to the sphere and the earth i.e. … So, the Potential difference becomes: $$V=\frac{KQ}{r}-\frac{KQ}{x}$$
And as $x$ approaches $r$ (the conductor touches the surface), the potential difference should become zero and no charge should actually …
