Unlike charges attract. Now here is my question, is this a phenomenon of Newton's third Law? I couldn't ask my lecturer because I had to run to another class for a quiz. It's friday and I don't want to ruin his friday.
The "repelling" force is a real right?
Like charges repel each other because they have the same type of charge, either positive or negative. This results in a force of repulsion between them. On the other hand, unlike charges attract because they have opposite charges, resulting in a force of attraction between them.
The concept of like charges repelling and unlike charges attracting is based on the fundamental principle of electricity, also known as Coulomb's law. This law 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. Therefore, like charges repel because they have the same charge and unlike charges attract because they have opposite charges.
The force of repulsion or attraction between two charged objects is inversely proportional to the square of the distance between them. This means that as the distance between the two objects increases, the force of repulsion or attraction decreases. This is why we can observe a stronger force between two charged objects when they are closer together.
No, two objects with the same type of charge will always repel each other. This is because like charges always repel each other according to Coulomb's law. In order for two objects to attract each other, they must have opposite charges.
The concept of like charges repelling and unlike charges attracting can be observed in everyday objects that have static electricity. For example, when you rub a balloon on your hair, the balloon becomes negatively charged and your hair becomes positively charged. Since like charges repel, the negatively charged balloon will repel the negatively charged hair, causing it to stand up. This is also why a balloon can stick to a wall after being rubbed on hair, as the opposite charges of the balloon and wall attract each other.
