The correct Answer is:
**Step-by-Step Solution:** 1. **Observation**: When we comb our hair during dry weather, we notice that sometimes the hair strands repel each other and seem to fly apart. 2. **Understanding the Phenomenon**: This behavior can be explained by the interaction of charges. When we comb our hair, the comb rubs against the hair, which can lead to the transfer of electrons between the two surfaces. 3. **Charge Transfer**: As we comb, some electrons from the hair may transfer to the comb or vice versa. This process causes the hair strands to become charged. 4. **Electrostatic Force**: When the hair strands become charged, they develop like charges (either both positive or both negative). According to the principles of electrostatics, like charges repel each other. 5. **Conclusion**: The force responsible for the hair flying apart is the **electrostatic force**. This force arises due to the repulsion between the similarly charged hair strands. **Final Answer**: The force responsible for the hair flying apart during dry weather while combing is the **electrostatic force**. ---
