1. The problem statement, all variables and given/known data We know that coulomb's law describes the force between two charged bodies as proportional to the magnitudes of the charges and inversely proportional to the square of the distance. Of course, like charges repel and unlike attract. Now theoretically, if we placed two opposite charges kilometers or even light-years apart, mathematically they would still feel an attractive force to each other. (Of course it is so minuscule, but still technically present.) As they start moving a tiny bit towards each other the force is greater because the distance is smaller. This increase in force would continue as they grew closer and closer together (since F(r)). Furthermore, if both were the same charge would they continue to repel each other indefinitely, even across monstrous distances like lightyears? 2. Relevant equations 3. The attempt at a solution just plugging in values to r (no matter how large) there is still a force felt. Also in the vacuum of space, there would be nothing to oppose the force so Fnet would zero be zero?
