Where's The Charge?

How is it possible that some material be charged positively and others charged negatively?

May be the charge is when $x_z\ge a_\psi$.

That the particle is in low oscillation.  An example of which is gravity that resonate at $7.489 Hz$.  In this case $a_\psi$ is in kilometers,

$f=n\cfrac{c}{2\pi a_\psi}$

$7.489=n\cfrac{c}{2\pi a_\psi}$

$a_\psi=n\cfrac{c}{2\pi.(7.489)}$,    $c=299792458$

$a_\psi=n.6371137$

when $n=1$

$a_\psi=6371 km$

which is mind blowing.  And Earth is just one big gravity particle.

Merry Christmas!

We experience the force field of these particles when we are in the red zone.  Is $x_z=a_\psi$?  If $x_z\ne a_\psi$ then as $\psi$ rotates about, the off center mass regions to the left and right of the mass will overlap.  Locations in this region will have two values of $\psi$ which cannot be the case.
As such, if $a_\psi$ and $\psi$ are valid solutions, then,

 $x_z=a_\psi$.  And we have,

And we have a big particle for Christmas.  Is it possible that  $a_\psi\ge x_z$?  We will not have the overlap issue as in this case, but there will be a gap in the field as shown in the post "Empty On The Inside".  $\psi$ is then a spherical shell around a center.
