Query: Treatment of $N$-dimensional Schr\"{o}dinger equation for anharmonic
  potential via Laplace transform   First time anharmonic potential $V(r)=ar^2+br-\frac{c}{r} \,,(a>0) $ is
examined for $N$-dimensional Schr\"{o}dinger equation via Laplace
transformation method. In transformed space, the behavior of the Laplace
transform at the singular point of the differential equation is used to study
the eigenfunctions and the energy eigenvalues.The results are easy to derive
and identical with those obtained by other methods.
