Which of the following materials is known to produce static electricity easily?

• A. Wool
• B. Metal
• C. Glass
• D. Water

Answer: (A)

Wool is known to produce static electricity easily due to its ability to lose electrons when rubbed against other materials. This characteristic is largely attributed to the triboelectric effect, which involves the transfer of electrons between materials with differing affinities for electrons. When wool is rubbed against another material, such as plastic or skin, it can acquire a positive charge, while the other material becomes negatively charged. This process occurs because wool has a high position on the triboelectric series, indicating that it readily gains a positive charge. Other materials listed may not easily produce static electricity. For example, metals are good conductors and do not tend to hold static charges, as they allow electrons to flow freely. Glass can generate static when rubbed, but it typically has a less pronounced tendency compared to wool. Water, being a polar molecule, tends to dissipate static charges rather than accumulating them, further highlighting the uniqueness of wool in producing static electricity easily.
