Coulomb's Law is a fundamental law of electrostatics that describes the force between two charged particles. It states that the 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.
Yes, the size of an object can affect its charge. The charge of an object is determined by the number of electrons it has. The more electrons an object has, the greater its charge will be. Therefore, a larger object with more electrons will have a greater charge than a smaller object with fewer electrons.
No, objects with the same charge repel each other according to Coulomb's Law. This is because like charges repel and opposite charges attract. So, if two objects have the same charge, they will repel each other.
The force between two charged objects decreases as the distance between them increases. This is because the inverse square law states that the force is inversely proportional to the square of the distance between the two objects. As the distance increases, the force decreases.
No, Coulomb's Law can be applied to any charged object, not just point charges. However, for larger objects, the calculation of the force between them becomes more complex as the charge is distributed over the entire object. In these cases, Coulomb's Law can be used to calculate the force between two point charges on the objects, and then the results can be applied to the entire object.
