  In this paper, we study the destruction of heavy quarkonium due to the
entropic force in a deformed $AdS_5$ model. The effects of the deformation
parameter on the inter-distance and the entropic force are investigated. The
influence of the deformation parameter on the quarkonium dissociation is
analyzed. It is shown that the inter-distance increases in the presence of the
deformation parameter. In addition, the deformation parameter has the effect of
decreasing the entropic force. This results imply that the quarkonium
dissociates harder in a deformed AdS background than that in an usual AdS
background, in agreement with earlier findings.
