   Two point charges are moved so that their separation doubles. What happens to the force between them?
   1. AIt halves, because force is inversely proportional to distance
   2. BIt doubles, because the charges have more space between them
   3. CIt falls to a quarter of its original value
   4. DIt quadruples, because force depends on the square of the distance
   5. EIt stays the same, because the charges themselves do not change
