C. greater than that at the surface of sphere B.

D. greater than or less than that at the surface of sphere B, depending on the charge on the spheres.

E. less than that at the surface of sphere B.

Explanation / Answer

1.In this case +q and +Q the force is resulsive this force is in the first quadrant and +q and -Q the force is attractive so the force is in the fourth quadrant. Take the resultante force we have.

C. horizontal to the right
