From the condition that these metric components should reduce to the field of a point mass located at the origin and contain Newton's equations of motion in the field of the spherical body, it follows that generally, f(r) is approximately equal to the Newtonian gravitational scalar potential in the exterior region of the body, [PHI](r) [12, 13].
