Another Loss – The classical Larmor formula for power radiated by an accelerated charged particle de q2|a|2 - dt = 67 60C3 (3) implies that the electron orbiting a proton in a hydrogen atom will quickly radiate away all of its kinetic energy and thus collapse. This failure of classical physics was one of the problems that led to the development of quantum mechanics. A classical hydrogen atom consists of an electron in a circular orbit around a proton, with the centrifugal force mev2/ro balancing the Coulomb force e2/(41 cori). Here ro = 5.3 x 10–1m is the electron's orbital radius, called the Bohr radius. The classical radiative lifetime, t, of such an atom is the electron kinetic energy E divided by the Larmor power radiated when r = ro. Estimate t.
