For pt.I see ibid., vol.31, p.1741-58 (1989). Concrete types of viscous-resistive ballooning MHD modes in a Tokamak are investigated. It is shown that the averaged ballooning equation of incompressible disturbances, derived in Part I, has an exact solution. The general dispersion equation of incompressible weakly ballooning modes is deduced, and different limits of this equation are considered. It is shown that viscosity results in stabilization of resistive-interchange instability in a high pressure plasma and decreases the ideal ballooning modes' increment.
