Q- The sun rises two hours earlier on Arunachal Pradesh as compared to Gujarat in the west but the watches show the same time. How does this happens?
Answer-
The main reason behind the sun rises two hours earlier on Arunachal Pradesh as compared to Gujarat in the west is that there is a longitudinal gap between Arunachal Pradesh and Gujarat that is about thirty degree. So that there was a gap between the sun rises in these two states of India.
Even there is a gap of thirty degree longitude but the time is always same because In India we used to follow the Indian Standard Time that was taken from the time of Standard meridian of India and hence, the watches show the same time in both states.
