Explain how the charges on objects determine the electric force between them. short pls
The charges on objects determine the electric force between them based on two fundamental principles: the like charges repel and opposite charges attract.
If two objects have charges of the same sign (positive or negative), they will exert a repulsive force on each other. This means that they will push away from each other, creating a force vector pointing in the opposite direction. The magnitude of the repulsive force is determined by the strength of the charges: the bigger the charges, the stronger the repulsion.
Conversely, if two objects have charges of opposite signs (one positive and the other negative), they will exert an attractive force on each other. This means that they will pull towards each other, creating a force vector pointing in the same direction. The magnitude of the attractive force is again determined by the strength of the charges: the bigger the charges, the stronger the attraction.
In summary, the charges on objects determine the electric force between them by either repelling or attracting each other based on their signs. The magnitude of this force depends on the strength of the charges involved.
