A proton is initially at rest. At time $t=0,$

$305\mathrm{.}556$ it is accelerated upward with an acceleration of $2\mathrm{.}4{10}^{18}\frac{m}{s^2}$ for a very short time. We

$266\mathrm{.}667$ make observations at location A$,10$ m from the proton as in the figure below. $3.366\mathrm{.}667a=2\mathrm{.}4{10}^{18}\frac{m}{s^2}$

What is the ratio of the magnitude of the radiative electric field $($when the pulse reaches A$)$ to the magnitude of static or Coulomb

$7.293\mathrm{.}333$ electric field at A due to the proton? Take the speed of light to be $c=3{10}^8\frac{m}{s}.$
