  We report some approximate analytic form of meson wave function constructed
upon solving Schrodinger equation with linear plus Coulomb type Cornell
potential. With this wave function, we study Isgur-Wise function and its
derivatives for heavy-light mesons in the infinite heavy quark mass limit. We
also explore the elastic form factors, charge radii and decay constants of
pseudoscalar mesons in this QCD inspired quark model approach.
