I used the whole distance in the kq/r squared equation and just solved for the electron.
Then I used half of r as the "r" in mv squared over r and also in the v = 2 x pi x r x f equation.
That sounds like a good way to solve the problem. I am not sure if you can just assume the positron is fixed at the origin. It sort of sounded like they were both rotating around the same center of mass, but I wasn't sure. Let me know if you come up with anything.
[b]1. A positron is an elementary particle identical to an electron except that its charge is
+ e. An electron and a positron can rotate about their center of mass as if they were a dumbbell connected by a massless rod.
What is the orbital frequency for an electron and a positron 1.70 nm...
