To determine which interactions will have an attractive electrical force, we need to look at the charges of the objects involved in each interaction. According to Coulomb's law, opposite charges attract each other, while like charges repel each other.

Here’s the breakdown of the interactions:

  • Interaction A: +4 (Object 1) and -3 (Object 2) → One positive and one negative charge (attractive force).
  • Interaction B: +1 (Object 1) and -1 (Object 2) → One positive and one negative charge (attractive force).
  • Interaction C: +1 (Object 1) and +1 (Object 2) → Both positive charges (repulsive force).
  • Interaction D: -1 (Object 1) and -1 (Object 2) → Both negative charges (repulsive force).

Now, we can summarize the attractive interactions:

  • Interaction A: attractive
  • Interaction B: attractive
  • Interaction C: not attractive
  • Interaction D: not attractive

Thus, the interactions with an attractive electrical force are A and B.

Therefore, the correct answer is O Interaction A and B.
