My teacher said if we could solve this we could get a free 100 on a test grade.

All i know is that you have to prove that q will oscillate forever

2 positive charges Q+ (that are not moving) are located on the x-axis on a distance d from an origin o, a third positive charge q with mass m is placed on the x-axis on a distance x (x much smaller than d)

Prove that the charge q will follow a simple harmonic oscillation (by very good approximation)

Well, I'm no physics geek but common sense tells me that since they're both positive charges, they'll want to continually repel each oher. >.>
Can't really prove it, though.

If Q1 is stronger than Q2 it will go towards Q2 if you know what i'm saying, I don't really get your question though. Didn't he say how strong they were and shit?

No, that's why he made it a Test grade if you got it.

Fel=Kq1q2\r^2 find the charges for each thing. Turns into Kq^2\r^2.
Something like that I believe. Then you also use the equation with distance in it, which I forget.

r=radius which is the distance in this case

I LUV SG WITH ALL MY HEART
