TBR Physics Book II page 128 Example 8.6b

Part of the explanation for why choices A and B are incorrect reads:



“The presence of positive charges in the medium would not impact the net force between the two particles although it would impact the net force [OF WHAT?]. This is because the force vectors in a charged environment can all be treated as independent of one another.”





Can someone explain this more clearly? I’m not sure I understand this part of the explanation.
