  The analysis of the secondary Bjerknes force between two bubbles suggests
that this force is analogous to the electrostatic forces. The same analogy is
suggested by the existence of a scattering cross section of an acoustic wave on
a bubble. Our paper brings new arguments in support of this analogy. The study
which we perform is dedicated to the acoustic force and to the scattering cross
section at resonance in order to highlight their angular frequency independence
of the inductor wave. Also, our study reveals that the angular frequency and
the amplitude of the induction pressure wave are not related. Highlighting this
analogy will allow us a better understanding of the electrostatic interaction
if the electron is modeled as an oscillating bubble in the vacuum.
