What is an inverse-square relationship between force and distance?
 a. A mathematical expression for the distance in terms of force instead of force in terms of distance, which is then squared.
  b. A relationship where increasing the distance by a factor increases the force by the square of the same factor.
  c. A relationship where one value decreases in proportion to the square of the factor by which the other value decreases.
  d. A relationship where the increasing the distance by a factor decreases the force by dividing it by the square of that same factor.
  e. A relationship where the square of force is proportional to the square of the distance.
