Two test charges are brought from infinity into the vicinity of a sphere of charge +Q. The first test charge, +q, is brought to point A; the second test charge, +2q, is also brought to point A. Compared with the electrostatic potential of +q, the electrostatic potential of +2q is
smaller
the same
greater
