A proton is initially at rest. At time t = 0, it is accelerated upward with an acceleration of 2.2 x 10 8 m/s for a very short time . We make observations at location A, 12 m from the proton as in the figure below. a = 2.2 x 1018 m/s2 . Proton A -----12 m - - - - -4 What is the ratio of the magnitude of the radiative electric field (when the pulse reaches A) to the magnitude of static or Coulomb electric field at A due to the proton? Take the speed of light to be c = 3 x 10 m/s
