we want to calculate the size of the net electric force on the rightmost proton. Assume that the baseline nearest neighbor force on the rightmost proton is 98 N, rightward, from the proton immediately to its left.
I need to find the size and direction of the net electric force on the rightmost proton
The diagram contains six electrons and protons it looks like this:
- - + - + +

hmmm.. ok ... 

i am assuming all of them are equidistant from each other.. 

now tell me this.. if force between two charges is 98 N.. what will be the force between them when the distance between them is doubled?
