<span>The distance between two objects is increased by three times the oringinal distance.  Since they were already separated by one time the original distance,
the additional three times the oringinal distance now puts them four times the original distance apart.
Whether we're talking about the gravitational forces of attraction or 
the electrical forces of attraction, either one is inversely proportional 
to the square of the distance between the objects.  
So changing the distance to four times the original distance causes 
the forces to become 1/4</span>² as strong as they were originally.  
The forces become 1/16 of their original magnitude.<span>
