$$D^a D_a V= 4 \pi V( \rho +3p)\\

R_{ab}=V^{-1}D_a D_b V+4 \pi ( \rho -p) g_{ab}$$

Where $$D_a$$ and $$R_{ab}$$ are the three dimensional covariant derivative and Ricci curvature tensor associated with $$g_{ab}$$.

Is this a homework question? Have you tried it yourself?

I
Is it possible to reduce or modify Einstein's Field Equations so they exactly mirror Newtonian gravity behavior?
