GPT-4o mini
When a plastic comb is charged by rubbing it with a cloth, it undergoes a process known as triboelectric charging. This process involves the transfer of electrons between the two materials—in this case, the plastic comb and the cloth.
Here’s how it works:
1. **Electron Transfer**: When the comb is rubbed against the cloth, electrons are transferred from one material to the other. Depending on the materials used, the comb may gain electrons and become negatively charged, while the cloth loses electrons and becomes positively charged.
2. **Static Electricity**: As the comb acquires a negative charge, it creates an imbalance in electric charge. This results in static electricity, which can create electrostatic forces.
3. **Attraction to Neutral Objects**: The charged comb can attract small neutral objects, such as bits of paper or hair, due to the electrostatic force. The negatively charged comb induces a positive charge on the nearby neutral objects, causing attraction.
4. **Demonstration of Electrostatic Principles**: This phenomenon is a common demonstration of electrostatics and illustrates principles like charge conservation and the behavior of electric fields.
In summary, rubbing a plastic comb with a cloth charges the comb through electron transfer, leading to static electricity and attractive interactions with nearby neutral objects.
