Pair A

Answer 1

To determine which pair of objects will have an attractive electric force, we need to consider the charges of the objects.

An attractive force occurs between opposite charges (negative and positive).

Let's analyze each pair:

- **Pair A:** Object 1: -2 (negative), Object 2: -1 (negative) → Both are negative, so they will repel each other.
- **Pair B:** Object 1: -3 (negative), Object 2: +1 (positive) → One is negative and the other is positive, so they will attract each other.
- **Pair C:** Object 1: +3 (positive), Object 2: +1 (positive) → Both are positive, so they will repel each other.
- **Pair D:** Object 1: +1 (positive), Object 2: +2 (positive) → Both are positive, so they will repel each other.

The only pair that will have an attractive electric force is **Pair B**.
