Question
Answer carefully:
What is the work done by the field of a nucleus in a complete circular orbit of the electron? What if the orbit is elliptical?
Solution
The initial and final position for any complete orbit is same and hence W=0. Electron will remain in the same energy state.
No matter what is the shape of the orbit, work done for any complete orbit is always zero.
