  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 use
linear cum Coulombic potential and opt firstly the Coulombic part as parent and
then linear part as parent.The results show that charge radii and form factors
are quite small for Coulombic parent case than the linear parent. Also, the
analysis leads to a lower as well as upper bound on the four momentum transfer
Q2 hinting at a workable range of Q2 within this approach which may be useful
in future for experimental analysis. Comparision of both the options prefer the
linear parent.
