When negative charges is created in the comb by rubbing it with hair and pieces of paper are exposed to the electric field created by the charge, the part of paper closer to the comb will be positively charged due to electromagnetic induction, and the farther would be negatively charged, causing the paper to be attracted to the comb.

**Determining the charge on a comb**
To determine whether a comb has a positive or negative charge, we can conduct a simple experiment using a piece of paper. When a comb is rubbed against hair, it creates a phenomenon called triboelectric charging, which involves the transfer of electric charges between two materials in contact. In this case, the comb and the hair act as the two materials.
**Triboelectric series**
Before delving into the experiment, it is essential to understand the concept of the triboelectric series. The triboelectric series is a list of materials arranged in order of their tendency to gain or lose electrons when they come into contact with each other. The materials at the top of the series tend to lose electrons and become positively charged, while those at the bottom tend to gain electrons and become negatively charged. For example, glass and human hair are near the middle of the series.
**Experiment procedure**
1. Take a comb and rub it against dry hair for about 30 seconds.
2. Hold the charged comb near a neutral piece of paper, without touching it.
3. Observe the behavior of the paper.
**Explanation of the results**
If the comb has a positive charge, it will attract the piece of paper. On the other hand, if the comb has a negative charge, it will repel the paper.
When the comb is rubbed against the hair, electrons are transferred between them due to the difference in their positions on the triboelectric series. This transfer of electrons leaves the comb with a net charge.
**Significance of the paper's behavior**
If the comb attracts the piece of paper, it indicates that the comb has a positive charge. This occurs because the comb has gained electrons from the hair, making it negatively charged. The piece of paper, being neutral, is attracted to the comb because opposite charges attract each other.
If the comb repels the piece of paper, it signifies that the comb has a negative charge. In this case, the comb has lost electrons to the hair, resulting in a positive charge. The similarly charged comb and paper repel each other due to the principle that like charges repel.
**Conclusion**
By observing the behavior of a piece of paper near a charged comb, we can determine whether the comb has a positive or negative charge. If the paper is attracted to the comb, it is positively charged, whereas if it is repelled, the comb is negatively charged. This simple experiment allows us to identify the type of charge on the comb based on the principles of triboelectric charging and the behavior of electrically neutral objects.
