k varies

No, the electrostatic CONSTANT does not vary. That's why they
call it a constant.

but never G:

1. k ***VARIES**** depending on the density(or structure) of the other
charges in the medium (since medium's are made of electrons and
protons) excluding Q&q.

No, it doesn't.

But k will certainly have different values in different media, since it
depends on the total permittivity of the medium.

Sorry... all media manufacturers get thier electrons from the
same supplier.

That's a poor explanation Sue, that link simply explains that "k" is
constant in space THEREFORE FOR THE ELECTRIC FORCE EXCERTED BETWEEN TWO
CHARGES IN ***AIR*** OR ***WATER*** IS *********NOT THE SAME*********
AS THE ELECTRIC FORCE EXCERTED BETWEEN TWO CHARGES IN SPACE: F =
KQq/R^2 (K VARIES WITH THE MEDIUM.....

....MEANING K VARIES WITH THE PRESENCE OF OTHER CHARGES IN THE SAME
REGION WHERE AS "G" DOES NOT VARY WITH THE PRESENCE OF OTHER
OBJECTS(MASSES) IN THE SAME REGION OF M&m (F= GMm/R^2) ).

You just answered your own question so I contend the URL is
effective. ;-)

k is sumed over all space because it is radiative.
G is sumed over all the matter because it is induced.


coils induce magnetism or current, G is neither

You have to apply forces to move a mass from moon to earth.

not if there's no moon and only earth & mass

You do not have to apply force to move a charge from one
plate to another plate of a charged capacitor.


WELL DONE!

That's because the attractive charge force along the wire is stronger
then the attractive charge force between the dielectric plate.....

Therefore "k" indeed varies with the medium (dielectric medium versus
copper medium) and the main difference between mediums is the electron
density(& proton) that surrounds Q&q!

Where as "G" remains constant regardless of the other planets(objects)
or mass densities that surround M&m!

F= k_medium (Qq/r^2) F = G_invariant (Mm/r^2)

So... You see some important difference in the behavior
of fundamental and composite particles ?
