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

The analysis of the Tajmar-de Matos experiment would
indicate otherwise.


cooling reduces motion such as freezing your food slows down the
rotting process.

supercooling reduces resistivity....whatever that means since it's only
a terminology, I guess it helps the electron jump to it's neighjbor
valences with less interference from other electrons of the neighbors
atom?

eitherway by INCREASING the MOTION gradually (spinning motion),

you may also be gradually contradicting the FREEZING MOTION of the
superconductor therefore it may still be an electromagnetic effect.

(Brief from above: gradually increasing motion of spin may be
gradualliy negating the freezing motion of supercooling effect).




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

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

If you can remove the moon but leave the debris on its
surface in place I'll accept that. Something tells me
the debris is going to tag along. :o)

?? I don't know what you were getting at since you started the debate
but likewise you if you can remove a positive charge but leave it's
pairing negative charge in place I'll accept that also????

The original point was the need to apply a force. Reconsidering,
I should have offered something showing the homogenity of
a sea of charges as opposed to the homogenity of a sea of
masses. That occured to me in reading the Randy's post
which you reference below.





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 ?

k even varies with the person that is using it, which is why you
have to be careful about the assumptions made in different
unit systems.

Well according to Randy in another thread k in F= k Qq/r^2 remains the
constant permittivity of space REGARDLESS of which medium it's in, I
find that illogical (why would the velocity decrease due to
permittivity but not the force of a charge.....especially since the
main difference between mediums is the charge density)?

Yes... that is a good example to disassemble because we have
Fitzpatrick's rigourous formalism that isn't jumping between
unit systems and it based in proven plasma theory.

Read his page carefully noting how he considers currents and
magnetic effects in the dielectric. Many discussions don't do
that and it contributes immensly to all the confusion that
surrounds the issue.

Sue...


<< Any discussion of magnetism is complicated because the
physical notation for magnetic fields is not standardized.
mks-SI system regards magnetism as an effect of electric currents
- where as -
cgs system begins with forces between poles >>

So it is imprudent to accept the assumptions of a particular
metrology, especially when you have evidence the assumptions
may not hold in practice.
