  We consider a static and axially symmetric metric containing two quadrupole
parameters. In the present contribution, we study the quadrupole moments
constraints on the properties of the relativistic accretion disc models, also
explore the relation of oscillatory frequencies of charged particles to the
frequencies of the twin high-frequency quasi-periodic oscillations observed in
some microquasars. We also compare the results with Schwarzschild and Kerr
metrics.
