Tidal stripping will occur when tidal force exceed gravitational
As with mergers, tidal interactions may have relatively short timescales in clusters; potentially more likely in cluster outskirts.
In cluster environment, can have galaxy-galaxy tidal forces and galaxy-cluster tidal forces, but latter are expected only to be significant near cluster center.
The expression for ram pressure is:
Ram pressure expected to be more significant in higher gas density environments, e.g. centers of clusters. Timescale for gas removal are relatively short, e.g. compared to tidal removal.
