  Using the gauge-gravity duality we have obtained the potential between a
heavy quark and an antiquark pair, which is moving perpendicular to the
direction of orientation, in a strongly-coupled supersymmetric hot plasma. For
the purpose we work on a metric in the gravity side, {\em viz.} OKS-BH
geometry, whose dual in the gauge theory side runs with the energy and hence
proves to be a better background for thermal QCD. The potential obtained has
confining term both in vacuum and in medium, in addition to the Coulomb term
alone, usually reported in the literature. As the velocity of the pair is
increased the screening of the potential gets weakened, which may be understood
by the decrease of effective temperature with the increase of velocity. The
crucial observation of our work is that beyond a critical separation of the
heavy quark pair, the potential develops an imaginary part which is nowadays
understood to be the main source of dissociation. The imaginary part is found
to vanish at small $r$, thus agrees with the perturbative result. Finally we
have estimated the thermal width for the ground and first excited states and
found that non-zero rapidities lead to an increase of thermal width. This
implies that the moving quarkonia dissociate easier than the static ones, which
agrees with other calculations. However, the width in our case is larger than
other calculations due to the presence of confining terms.
