An isolated negative point charge is fixed at O. A small positive bead is held at P, to the right of O. It is then moved to Q, which is to the left of O and farther from O than P.
Which describes the electric force on the bead at Q compared with its force at P?
Same direction; smaller magnitude.
Opposite direction; larger magnitude.
