These special results can easily be extended to the more general case of different means.
In the general case, however, the expression above is no longer the solution of the problem.
However, this property does not hold in the general case.
It is easy to guess that in the general case one would have, instead, the potential due to all other charges.
We now turn to the general case, and approach it by means of a simple example.
However, in the more general case this is not possible.
"I don't see why he would have lived in conditions like that for two years when it was far from the general case".
These would be special cases of the more general case analyzed here.
However, no general case can be made for such a switch.
The same result can be obtained in the more general case.
