    Growth rates of quasi-interchanges and quasi-helicals in the presence of a centrifugal potential are obtained in the tokomak approximation, using the analytical solution of motion. The centrifugal force makes a condition for stability and growth rates of quasi-interchanges in a compressible plasma more stringent and more dangerous respectively than in a incompressible one. For the very small increasing values of the centrifugal force quasi-helicals and type-2 modes of quasi=interchanges become more dangerous, while type-1 mode become less dangerous. For greatly increasing values of the centrifugal force both quasi-interchanges and quasi-helicals have higher growth rates and the greater unstable region of K.B, where k and B are the wavevector of the perturbation and the magnetic field, respectively.
