If,
mev2re=Av2+FLe−FLp−FT
FT=TeTn4πτor2e
FLe=πn−1∑i=1q24πεor2ei=n−1∑i=1q24εor2ei
FLp=πnq24πεor2e=nq24εor2e
the quadratic equation or re becomes,
(Av2+n−1∑i=1q24εor2ei)r2e−mev2re−nq24εo−TeTn4πτo=0
(Av2+n−1∑i=1q24εor2ei)r2e−mev2re−14{nq2εo+TeTnπτo}=0
The y-intercept is negative always.
If we rearrange the terms again,
Av2r2e−mev2re+14{n−1∑i=1q2εor2eir2e−nq2εo−TeTnπτo}=0
We may get a zero intercept and even a double root, but the term,
n−1∑i=1q2εor2eir2e
that appears as part of the y-intercept is really awkward and wrong.
There is only one thing to do, summon the spirit of Newton,
mev2re=Av2+FLe+FG−FLp−FT
FG=Gn.mpmer2e
(Av2+n−1∑i=1q24εor2ei)r2e−mev2re+14{4nGmpme−nq2εo−TeTnπτo}=0
then the y-intercept can be zero, positive to allow for two roots of re and even positive enough to result in a double root.
If we put in the numbers, however, it seems that we need a positive attractive force desperately.
