We use VIPT in calculating the elastic form factors and charge radii of D,Ds, B, Bs and Bc mesons in a QCD inspired potential model. For that we uselinear cum Coulombic potential and opt firstly the Coulombic part as parent andthen linear part as parent.The results show that charge radii and form factorsare quite small for Coulombic parent case than the linear parent. Also, theanalysis leads to a lower as well as upper bound on the four momentum transferQ2 hinting at a workable range of Q2 within this approach which may be usefulin future for experimental analysis. Comparision of both the options prefer thelinear parent.
