Final answer:
The repulsion effect between two objects can be accomplished by the repulsive electrostatic force between them. This force is due to the interaction of like charges, which cause the objects to push away from each other.
Step-by-step explanation:
The repulsion effect between two objects can be accomplished by the repulsive electrostatic force between them. This force is due to the interaction of like charges, which cause the objects to push away from each other. According to experimental findings, the magnitude of this force decreases as the square of the distance between the objects increases. For example, when the distance between two objects is doubled, the force between them decreases to one fourth of its original value.
