Query: Spherically Symmetric Considerations for a Higher Order Theory of
  Gravitation   A higher order theory of gravitation is considered which is obtained by
modifying Einstein field equations. The Lagrange used to modify this in the
form a polynomial in (scalar curvature) R. In this equation we have studied
spherical symmetric metric.
