In(adsbygoogle = window.adsbygoogle || []).push({}); General relativity: an introduction for physicists, the authors derive Newtonian gravity from the EFE, but then they also give a short statement that inserting in the cosmological constant derives down to:

[tex]

\vec{g}=-\nabla\Phi=-\frac{GM}{r^{2}}\hat{\vec{r}}+\frac{\Lambda c^{2}r}{3}\hat{\vec{r}}.

[/tex]

I don't see how they end up with a 3 in the denominator. Probably am missing something simple. Any help?
