An electron (charge -e, mass m) and a positron (charge +e, mass m) revolve around their common center of mass under the influence of their attractive coulomb force. Find the speed of each particle v in terms of e, m, k and their separation r ?
F= kq1q2/ r^2
The Attempt at a Solution
Can you guys give me a hint on this one ? Should I find the angular speed then ?
