I would say the magnitude of the charges and the distance between them.


The force between, say, two charges is known as Coulomb's Force and is directly proportional to the product of the charges (in modulus) and inversely to the square of their distances.
#k# is a constant
#r# the separation between the two charges (#r# because of the "usual" spherical symmetry of the phenomenon).

This is the case of your charges in vacuum. The presence of a dieletric (a substance in which your charges are immersed) qould change the constant #k# but not the above considerations on magnitudes of charges and distance.
