84. An electron oscillates back and forth along the + and - x-axes, consequently emitting electromagnetic radiation. Which of the following statement concerning the radiation is NOT true?
(A) The total rate of radiation of energy into all directions is proportional to the square of the electron's acceleration.
(B) The total rate of radiation energy into all directions is proportional to the square of the electron's charge.
(C) Far from the electron, the rate at which radiated energy crosses a perpendicular unit area decreases as the inverse square of the distance of the electron.
(D) Far from the electron, the rate at which radiated energy crosses a perpendicular unit area is located on the + or - x-axes.
(E) Far from the electron, the radiated energy is carried equally by the transverse electric and the transverse magnetic fields.
