The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges
10.
To charged objects will attract each other if they have opposite charges (one is positive and the other is negative).
11.
Two charged objects will: repel each other if they have like charges (they are both positive or both negative).
