A classical model for the hydrogen atom consists of a singal electron of mass m_(e) in circular motion of radius r around the nucleous (proton). Since the electron is accelerated, the atom continuously radiates electromagnetic waves. The total power P radiated by the atom is given by P = P_(0)//r^(4) where P_(0) = (epsi^(6))/(96pi^(3)epsi_(0)^(3)c^(3)m_(epsi)^(2)) (c = velocity of light) (i) Find the total energy of the atom. (ii) Calculate an expression for the radius r(t) as a function of time. Assume that at t = 0 , the radiys is r_(0) = 10^(-10)m . (iii) Hence or otherwise find the time t_(0) when the atom collapses in a classical model of the hydrogen atom. Take: [2/(sqrt(3))(e^(2))/(4piepsi_(0))1/(m_(epsi)c^(2)) = r_(e) ~~ 3 xx 10^(-15) m]
