Refer to the following information for the next three questions.

According to Coulomb's Law,
if the charge of either the nucleus or the orbital electron were greater, the force between the nucleus and the electron would be
 
if the distance between the nucleus and electron were greater the force would be
 
if the distance between the nucleus and electron were doubled, the force would be
 
Refer to the following information for the next four questions.

Consider the electric force between a pair of charged particles a certain distance apart. By Coulomb's Law:
if the charge on one of the particles is doubled, the force is
 
if, instead, the charge on both particles is doubled, the force is
 
if instead the distance between the particles is halved, the force is
 
if the distance is halved, and the charge of both particles is doubled, the force is ____ times as great.
