Let's take two protons (i.e. two composite particles with mass m~1.6e-24g and electric charge q=1.6e-19 Coulomb).
The electric repulsion force wants to pull them apart while their gravitational attraction wants to join them.

Is there a distance at which the gravitational pull and the electrostatic push are equal, and the two particles can remain in equilibrium (in the absence of all other bodies in the universe)?

Here's the calculation for the #RF field model derived from behaviour near the axis. The RF multipole case got quite complicated, maybe there's a simpler way but I wanted to see if this method, which I'd used for magnetostatics (magnet field models), could be generalised.

It is a rare and beautiful occasion when theoretical physics and practical engineering seamlessly converge to realize concepts previously banished to the realms of magic and science fiction.

I wanted a simple but smooth electromagnetic field model of an RF cavity for use in particle tracking. I didn't want to design the whole cavity yet, so assumed a particular on-axis field function and then used Maxwell's equations to give a power series in radius. (I loosely based this on a similar note for magnet fields that I wrote in 2013).
