It seems that classical electrodynamics predicts that there will be no deflection. The electromagnetic field in the laser beam and the static electric field of the ball do not interact with
each other (E&M theory is linear). On the other hand, quantum electrodynamics has interactions between charges and photons (i.e., those responsible for the Compton effect).
