Explanations:The question revolves around the geographical position of Arunachal Pradesh and Gujarat in relation to the sun's movement and the concept of time zones in India. Arunachal Pradesh is located in the eastern part of India, while Gujarat is in the western part. Due to this geographical difference, the sun rises earlier in Arunachal Pradesh compared to Gujarat. This is a fundamental concept in geography and time zones.
India follows a single time zone, which is the Indian Standard Time (IST). This means that regardless of the geographical location within the country, all watches show the same time. The IST is based on the longitude of 82.5°E, which passes through the city of Allahabad. This single time zone is maintained for administrative convenience and uniformity across the country.
The statement A is true because the sun indeed rises two hours earlier in Arunachal Pradesh compared to Gujarat. This is due to the longitudinal difference between the two states. The eastern part of India, where Arunachal Pradesh is located, is closer to the sun's rising point, leading to an earlier sunrise. On the other hand, Gujarat, being in the western part, experiences a later sunrise.
However, the reason R is false because it incorrectly suggests that the watches in both states show the same time due to the geographical position. In reality, the watches show the same time because India follows a single time zone, not because of the geographical position. The geographical position affects the sunrise time but not the time shown on the watches.
It is important to understand that while the geographical position affects the natural phenomena such as sunrise and sunset times, the administrative and practical aspects of timekeeping in a country are managed through a single time zone. This concept is crucial for understanding the relationship between geographical location and time in a country like India.
