We make a critical analysis on the free parameters of the Cornell potential −4αs/3r+br+c and provide a parameterisation space for the strong coupling constant αs and the constant shift c for choosing linear part as perturbation in the potential model. In the analysis of heavy-light mesons (D,Ds,B,BsandBc), we have found a wide range of values for the coupling constant i.e 0.20≤αs≤0.64 with −1.2≤c≤−0.66 which can be used to treat the confining part as perturbation.
