	I have a physics question, but I've cleverly surrounded it with random life stuff so it doesn't look like I'm exploiting this forum for my own ends.

I still hate Penny Arcade's new design. The colors are ugly, yes, but I think the worst thing, the thing that is keeping me from reading the news post every day, is the fact that the text is all on the left side. For some reason it makes me feel like I'm standing on my head or wearing my watch on the wrong arm. My work phone number must have previously belonged to a mime that worked for the Dept of Education, judging from 90% of the phone calls I get. I was reading PhysicsWeb today. There was an article about a new technique to measure the dipole of the electron. Hey, I know what a dipole is! This is precisely one of the reasons I started studying physics--so I could read articles like this and have a clue what was going on beyond "day-mn, them thar science dudes shure are smart, hyuck" An electron is constrained to the central axis of the ring of charge of radius R. Show that the electrostatic force exerted on the electron can cause it to oscillate through the center of the ring with an angular frequency ω = sqrt(keq/(mR3)) where q is the ring's charge and m is the electron's mass. I understand the problem, but I don't see how I'm equipped to solve it. The only oscillation I've done is SHM (Simple Harmonic Motion) which requires the force to be linearly related to the distance. That's not the case here. The queue's been really empty for the last couple days. I'm not sure what to think about that.
