Classical nature of the hydrogen atom

  1. Apr 29, 2007 #1
    1. The problem statement, all variables and given/known data
    According to the classical nature of the hydrogen atom an electron in a circular orbit of radius 5.3*10^-11m around a proton fixed at the centre is unstable. If it is true, how long would it take for the electron to collaspse into the proton?

    2. Relevant equations
    There is a hint: "Use integral calculus to solve the classical expression for radiation from an accelerated charge"

    3. The attempt at a solution
    I really don't know where to start... can anyone care to tell me what is the "classical expression for radiation"?
