Gravitational lensing - 2 questions

[Dmitry67]

Observer O sees object S in the imaginary position S', because of the gravitational lensing caused by the heavy mass M.

Question 1.
If O is positively charged and S is negatively charged, in what difrection acts the coloumb force - S or S' ?

Question 2.
If S is massive (but is still much lighter then M) what is a direction of additional grvitational force (well, it is not the force but it is not important here) from S?

In such cases (when there re no repplies) I wonder if I am asking something too smart or too stupid :)
