To determine the amount of force between two objects, you need to consider the charges on the objects and the distance between them. The strength of the electrical force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Let's analyze each interaction:
Interaction A: The charges on Object 1 and Object 2 are +2 and -2, respectively, and the distance between them is 1. Therefore, the force can be calculated as (2 * -2) / (1^2) = -4.
Interaction B: The charges on Object 1 and Object 2 are +1 and -1, respectively, and the distance between them is 1. Therefore, the force can be calculated as (1 * -1) / (1^2) = -1.
Interaction C: The charges on Object 1 and Object 2 are +2 and -2, respectively, and the distance between them is 4. Therefore, the force can be calculated as (2 * -2) / (4^2) = -1/8.
Interaction D: The charges on Object 1 and Object 2 are +1 and -1, respectively, and the distance between them is 4. Therefore, the force can be calculated as (1 * -1) / (4^2) = -1/16.
Based on these calculations, we can see that the force is the strongest in Interaction A, with a value of -4.
Therefore, the correct answer is Interaction A.
