A theoretical study has been undertaken on the influence of neutral collision frequency and viscous force on Jeans instability in radiative magnetized quantum plasma. A study was conducted using linearized quantum magneto-hydrodynamic equations. A general dispersion relation is acquired employing the normal mode analysis technique and the dispersion relation is discussed for longitudinal and transverse propagation. The altered general dispersion relation is derived and discussed to acquire Jean's state of instability by containing the magnetic field and quantum correction. The numerical findings are provided to demonstrate the impact of these changes on the rate of expansion of Jeans instability. The figure captions include too many details in this paper which represent that all considered parameters have a stabilizing or destabilizing effect on the growth rate of instability. The present study is suitable to understand the phenomena of acoustic waves in astronomical space plasma science.
