AP Physics C: E&M
9.3 Conservation of Electric Energy
9.2 Electric Potential
9.1 Electric Potential Energy
In a classical model of the hydrogen atom, an electron of charge \(-e\) and mass \(m\) orbits a stationary proton of charge \(+e\) in a circular path of radius \(r_0\). The electron is then transferred to a stable circular orbit of radius \(2r_0\). What is the minimum work that an external agent must perform to remove the electron from this outer orbit to infinity and bring it to rest?
