I'm not sure if the net field is meaning the net field of each specific point or all the points...although now that I think about it, specific points makes a whole lot more sense.


Is a "charge" the imaginary protons which each point is?

EDIT: I should probably mention that we went over the above in class--so I'm worried about understanding the wording of the question should another one pop up somewhere on a quiz or test or something. I'm not certain about the 1/9th thing, but based on memory and based on the whole if something is a certain distance away from something else, the force is 1/r² it seems right.
