The charm quarks are expected to be produced at the initial fusion of the ultrarelativistic heavy-ion collisions. Just after the production, they will propagate through the Quark Gluon Plasma (QGP) and will loose energy by colliding with quarks and gluons and radiating gluons. We calculate the nuclear modification factor $R_{AA}$ of charm quarks, produced from the initial fusion of partons in a nuclear collision, at $\sqrt{s_{NN}}$=2.76 TeV Pb-Pb collision at LHC at more forward rapidities . At the relativistic heavy-ion collisions, nuclear shadowing effect will also play an important role. In this study, we take in to account the effect of collisional and radiative energy loss of the charm quarks while passing through the QGP and also the gluon shadowing effect while calculating $R_{AA}$. We have considered some of the important formalisms available in the literature for the calculation of medium-induced radiative and collisional energy loss. The shadowing effect is introduced by using EKS 98 parameterization for structure functions.
