We theoretically investigate the nonlinear dynamics of a quadratically coupled opto-electromechanical system in which the movable end is capacitively coupled to an external charged object. Additionally, a third-order Kerr nonlinear medium is introduced into the cavity. We study the effect of optomechanical, Kerr type, and Coulomb coupling strength on optomechanically induced absorption(OMIA) shown by the output probe field of the system. We also obtain the Normal mode splitting(NMS) dynamics, which shows a robust character that can outweigh the nonlinear quadratic optomechanical coupling compared to the anharmonic mechanical cubic parameter in the cavity’s displacement spectrum. Our results suggest that the system can be employed in precision measurements of electrical charges, optical switching, sensing and studying population dynamics in cavity quantum optomechanics.
