To determine which pair of objects will have an attractive electric force, we need to recall that opposite charges attract while like charges repel.

Let's examine each pair:

Pair A: Object 1 has a charge of -2 and Object 2 has a charge of -1. Both are negative charges, so they will repel each other.
Pair B: Object 1 has a charge of -3 and Object 2 has a charge of +1. Since one is negative and the other is positive, they will attract each other.
Pair C: Object 1 has a charge of +3 and Object 2 has a charge of +1. Both are positive charges, so they will repel each other.
Pair D: Object 1 has a charge of +1 and Object 2 has a charge of +2. Both are positive charges, so they will also repel each other.

Only Pair B (with charges -3 and +1) will have an attractive electric force.

The correct answer is:

Pair B
