A proton is initially at rest. At time t = 0, it is accelerated upward with an acceleration of 1.2 x 10¹8 m/s2 for a very short time. We make observations at location A, 14 m from the proton as in the figure below. a = 1.2 × 10¹8 m/s² • Proton +----- 14 m A 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?
