Which pair of objects will have an attractive electric force?
pair Object 1 Charge Object 2 Charge
A -2 -1
B -3 +1
C +3 +1
D +1 +2
Pair B will have an attractive electric force as the charges are of opposite polarity (-3 and +1).
thank you and your sure this is right
Yes, I am sure. Opposite charges (positive and negative) attract each other, while similar charges (positive and positive or negative and negative) repel each other. In pair B, we have a negative charge of -3 and a positive charge of +1, so they will attract each other.
To determine which pair of objects will have an attractive electric force, you need to consider the nature of electric charges.
Opposite charges attract each other, while like charges repel each other.
In the given choices, we have four pairs of objects and their corresponding charges:
Pair A: Object 1 Charge = -2, Object 2 Charge = -1
Pair B: Object 1 Charge = -3, Object 2 Charge = +1
Pair C: Object 1 Charge = +3, Object 2 Charge = +1
Pair D: Object 1 Charge = +1, Object 2 Charge = +2
Let's analyze each pair:
Pair A has both objects with negative charges (-2 and -1). Since these charges are the same, they will repel each other, not attract. Therefore, Pair A does not have an attractive electric force.
Pair B has Object 1 with a negative charge (-3) and Object 2 with a positive charge (+1). As we mentioned earlier, opposite charges attract. In pair B, the charges are opposite, so they will have an attractive electric force.
Pair C has both objects with positive charges (+3 and +1). Since these charges are the same, they will repel each other, not attract. Therefore, Pair C does not have an attractive electric force.
Pair D has both objects with positive charges (+1 and +2). Since these charges are the same, they will repel each other, not attract. Therefore, Pair D does not have an attractive electric force.
Based on this analysis, the pair of objects that will have an attractive electric force is Pair B, where Object 1 has a negative charge (-3) and Object 2 has a positive charge (+1).
