In electrostatics, opposite charges attract and like charges repel. Let's analyze each interaction:
- Interaction A: +4 and -3 (opposite charges) — This will have an attractive electrical force.
- Interaction B: +1 and -1 (opposite charges) — This will also have an attractive electrical force.
- Interaction C: +1 and +1 (like charges) — This will have a repulsive electrical force.
- Interaction D: -1 and -1 (like charges) — This will also have a repulsive electrical force.
The interactions that will have an attractive electrical force are A and B.
Therefore, the correct response is:
Interaction A and B.
