In this work, we study a mathematical planar pendulum whose support point is positioned equidistant between two vertical and uniformly electrically charged wires. Its bob carries an electric charge and, its support point oscillates vertically, following a harmonic law of motion. We study the dynamics of such phenomenon and the parametric resonances of the equilibria. Moreover, we obtain the surface in the parameter space (since such system presents three parameters) which separates the region of stability from the region of instability. On the particular case of zero charge, we obtain the boundary curves of the stability/instability of Matheiu equation.
