Query: Application of Modified Hypervirial and Ehrenfest Theorems and Some of
  its Consequences   It is well-known that owing to the restricted character of the area
additional surface terms emerge in the traditional form of hypervirial and/or
Ehrenfest theorems. Especially, when one considers spherically symmetric
potentials and operators the radial distance in spherical coordinates is
restricted by a half-plane. Therefore the extra term arises in this case as
well in view of boundary conditions at the origin of coordinates. We analyse
the role of this term for various model-potentials in the Schrodinger equation.
We consider regular as well as soft-singular potentials and show that the
inclusion of this extra term is very essential in obtaining correct physical
results. Among the well-known results some new ones are also derived.
