A small positive bead is placed first at P and then at Q in the same electric field. The field lines point downwards at both positions but are closer together at P.
Which describes the electric forces?
Both forces act upwards; the force at P is greater.
Both forces act downwards; the force at Q is greater.
Both forces act upwards; the force at Q is greater.
Both forces act downwards; the force at P is greater.
