(abridged) We present the newly acquired data for an AstroSat/UVIT fieldcentered on a face-on spiral starburst galaxy UGC 10420, located in the clusterAbell 2199. We have analysed the FUV data for this field along with thearchival data from the Galex mission, optical photometric data from the SDSS,and low-frequency radio data from the LoTSS survey, respectively. The starswere separated from the galaxies using the SDSS pipeline classification, whilethe spectroscopic redshifts available for 35% of the detected UVIT sources wereused to identify member galaxies of the cluster Abell 2199. We find that (a)the non-cluster galaxies are on average fainter than the cluster galaxies atfixed magnitude, (b) stars and galaxies are indistinguishable in the r vs NUV-rplane, and (c) bright stars are ~1.5 mag bluer than the galaxies in the FUV-rvs NUV-r colour-colour plane. Besides UGC 10420 which is the only known clustergalaxy with an extended-UV disk, we identify five more galaxies with asymmetricFUV morphology and extended radio emission in this field. All the asymmetricmember galaxies of Abell 2199, lie within the virial boundaries of the cluster.This observation, together with the fact that these asymmetric cluster galaxieshave low-frequency radio tails or FUV emission pointing away from the clustercentre leads us to hypothesise that these galaxies are likely undergoingram-pressure stripping (RPS) under the influence of cluster-environment relatedmechanisms. A comparison of optical and FUV star formation rate of UVITdetected galaxies shows enhanced star formation in half of the RPS candidates,suggesting that environment-related mechanisms may lead to a burst of starformation in RPS galaxies. Our analysis indicates the presence of at least twomore groups or clusters at z~0.077 and 0.260, coincident with Abell 2199 alongthe line of sight of the field of view studied here.
