The pair of objects that will have an attractive electric force is Pair B, which consists of Object 1 with a charge of -3 and Object 2 with a charge of +1.
The electric force between two charged objects depends on the type and magnitude of their charges. According to Coulomb's Law, like charges repel each other, while opposite charges attract each other.
Looking at the given pairs:
Pair A: Object 1 has a charge of -2 and Object 2 has a charge of -1. Since both charges are negative, they have similar signs, which means they would repel each other. Therefore, Pair A does not have an attractive electric force.
Pair B: Object 1 has a charge of -3, and Object 2 has a charge of +1. Here, we have opposite charges, with one being negative and the other positive. Opposite charges attract each other, so Pair B does have an attractive electric force.
Pair C: Object 1 has a charge of +3, and Object 2 has a charge of +1. Both charges are positive, so they have similar signs and would repel each other. As a result, Pair C does not have an attractive electric force.
Pair D: Object 1 has a charge of +1, and Object 2 has a charge of +2. Both charges are positive, meaning they have the same signs and would repel each other. Therefore, Pair D does not have an attractive electric force.
So, the pair of objects that will have an attractive electric force is Pair B. The charges in Pair B exhibit opposite signs, resulting in an attractive electric force between the objects.
