  Comprehensive observations of galaxy clusters suggest that gas deficiency in
the galaxies could be due to ram pressure stripping due to the high-pressure
intra-cluster medium acting on the galactic discs. The presence of gas in
galaxies is essential for star formation. The net force due to ram pressure is
dependent on the ambient medium and the orbit followed by the galaxy as it
moves past the cluster medium. The current work deals with the effect of
non-radial orbits of galaxies and the inclination of the disc plane of galaxies
with the orbital plane on the mass of gas removed due to ram pressure. This
gives a realistic approach to understanding the process of ram pressure
stripping. The orbital parameters are extracted from EAGLE simulation data set
along with the mass distribution of the galaxies. The analytical model proposed
by Singh et. al. (2019) is modified appropriately to include the effect of the
inclination angle. The non-radial orbits and infalling galaxies not being
face-on decrease the amount of gas removed. Moreover, the inclination angle has
a pronounced effect on the stripping of gas in low-mass galaxies as compared to
high-mass galaxies with similar inclinations. The results show that the
efficiency of the ram pressure stripping can be much lower in some cases, and
hence gas in infalling galaxies can survive for much longer than expected from
a simple analysis.
