Claim: The distance between charged objects negatively affects the electrical force between them; as the distance increases, the electrical force decreases.
Evidence: In my observations, when two charged objects (such as two balloons rubbed on hair to create static electricity) were placed a few centimeters apart, they exhibited a strong repulsive force, causing them to move quickly away from each other. However, when I gradually increased the distance between the balloons to over a meter apart, the repulsive force diminished significantly, and they barely interacted.
Reasoning: The behavior observed aligns with Coulomb's Law, which states that the electrical force between two charged objects is inversely proportional to the square of the distance between them. This means that doubling the distance between the charged objects results in a force that is one-fourth as strong. Thus, the stronger interaction observed at a smaller distance indicates a greater electrical force, which weakens as the distance expands. Consequently, the evidence from my observations supports the claim that increasing the distance between charged objects leads to a decrease in electrical force.
