2. The sun rises two hours early in Arunachal Pradesh when compared to
Gujarat, but the watches show the same time how is it possible.
Answers
Answer:
From Gujarat to Arunachal Pradesh there is a time lag of two hours, but the watches show the same time because the time along the Standard Meridian of India (82° 30' E) passing through Mirzapur in Uttar Pradesh is taken as the standard time for the whole country.
There is a time lag of 2 hours from Gujarat to Arunachal Pradesh it means the sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the West but the watches show the same time the Earth takes 4 minutes to rotate through 1 degree of longitude therefore the time taken by the earth to rotate through 15 degree longitude is a 1 hour since, India has a longitudinal extent of 30 degree so there is a time difference of 2 hours between Arunachal Pradesh and Gujarat but the watches are set for all the parts of the country according to the Indian Standard Time measured at 82 and half degree longitude this is the reason why the watches show the same time everywhere in India
