To determine which two objects will have the strongest attractive force between them, we can apply Coulomb's Law, which states that the force between two charged objects is directly proportional to the product of the magnitudes of their charges and inversely proportional to the square of the distance between them.
Attractive forces occur between opposite charges. Based on the charges provided:
- Object A: +1
- Object B: +2
- Object C: -1
- Object D: -2
The combinations that will produce attractive forces are:
- Object A (+1) and Object C (-1)
- Object A (+1) and Object D (-2)
- Object B (+2) and Object C (-1)
- Object B (+2) and Object D (-2)
Now we can calculate the magnitude of the attractive force for each combination:
- For A and C: \(1 \times 1 = 1\)
- For A and D: \(1 \times 2 = 2\)
- For B and C: \(2 \times 1 = 2\)
- For B and D: \(2 \times 2 = 4\)
The strongest attractive force comes from the combination of object B and object D, which has a product of \(4\).
Therefore, the answer is:
object B and object D
