Objects with opposite charges, such as a negatively charged object and a positively charged object, interact through a fundamental electrostatic force. When an object possesses a negative charge, it means it has an excess of electrons. Conversely, a positively charged object has a deficit of electrons, creating a positive charge.
When these two objects come into proximity, the negative charge of the negatively charged object attracts the positive charge of the positively charged object. This attraction occurs because opposite charges tend to pull towards each other, leading to a force that draws the two objects closer together.
In summary, the interaction between objects with opposite charges results in an attraction, where the excess electrons of the negatively charged object are drawn towards the positive charge of the positively charged object.
