Query: RMS and charge radii in a potential model   The Dalgarno's method of perturbation is used to solve the Schrodinger's
equation with the Cornell potential $V(r)=-\frac{4\alpha_s}{3r}+br+c$. The
short range and long range effect of the potential is incorporated in the same
wave function by using two scales $r^S$ and $r^L$ as an integration limit. The
results for bounds on r.m.s. radii of various heavy flavored mesons are
reported. We have also showed the relation between r.m.s. and charge radius of
mesons.
