  In the context of higher dimensional braneworld scenario, the stabilisation
of extra dimensional modulus is an essential requirement for resolving the
gauge hierarchy problem in the context of Standard Model of elementary particle
Physics. For Randall-Sundrum (RS) warped extra dimensional model, Goldberger
and Wise (GW) proposed a much useful mechanism to achieve this using a scalar
field in the bulk spacetime ignoring the effects of backreaction of the scalar
field on the background metric. In this article we examine the influence of the
backreaction of the stabilising field on the stabilisation condition as well as
that on the Physics of the extra dimensional modulus namely radion. In
particular we obtain the modifications of the mass and the coupling of the
radion with the Standard Model (SM) matter fields on the TeV brane due to
backreaction effect. Our calculation also brings out an important equivalence
between the treatments followed by Csaki et.al. in \cite{kribs} and
Goldberger-Wise in \cite{GW1,GW_radion}.
