Help pls I’ll give extra points

A

Step-by-step explanation:

Let's go by process of elimination.

Two negatively charged objects will repel each other because they are the same charge, and like repels like. Opposites attract. Same principle for B.

For D, this is true because as the charge decreases, so does the strength of the force between the two objects. This is why you can push two weak magnets that have the same polar sides together, and why you can't with a stronger one.

This leaves us with A, and A is not true because force is inversely proportional to distance, and so if the distance is larger, the force is smaller, and if the distance is smaller, the force is larger. Like how 1/3 is bigger than 1/9.
