A small positive charge is placed in the electric field of a negatively charged sphere.
The small charge is then moved further away from the sphere.
Which statement describes the force on the small charge?
It is an attraction, and it gets stronger as the charge moves away
It is a repulsion, and it gets weaker as the charge moves away
It is an attraction, and it gets weaker as the charge moves away
It is a repulsion, and it stays the same as the charge moves away
