The aim of this paper is to examine the tidal forces occurred in Kiselev
black hole surrounded by radiation and dust fluids. It is noted that radial and
angular component of tidal force change the sign between event and Cauchy
horizons. We solve the geodesic deviation equation for radially free falling
bodies toward Kiselev black holes. We explain the geodesic deviation vector
graphically and point out the location of event and Cauchy horizons in it for
specific values of radiation and dust parameter.Comment: 20 pages, 10 figure
