What is the magnitude of the normal force?

Q. A positively charged ball hanging from a non conducting string is brought near a non conducting object.Based on the behavior of the ball-string combination,the ball is seen to be attracted to the object.From this experiment,it is not possible to determine whether the object is negatively charged or neutral.Why not? What additional experiment could help you decide between these two possibilities?
