Answer 1

The correct conclusion is that repulsive forces are stronger than attractive forces. This is because in interaction A, where the charges are opposite (+1 and -2), the force is weak, indicating an attractive force. In interaction B, where the charges are the same (+1 and +2), the force is strong, indicating a repulsive force.
