Abstract: We shall investigate the properties of a congruence of geodesics in theframework of Palatini fR theories.
We shall evaluate the modified geodesicdeviation equation and the Raychaudhuri-s equation and show that fR Palatinitheories do not necessarily lead to attractive forces.
Also we shall studyenergy condition for fR Palatini gravity via a perturbative analysis of theRaychaudhuri-s equation.
