1.	the sun rises 2 hrs earlier in arunachal pradesh as compared to gujarat in the west but our watches show same time . how does that happen ?
Answer» th in it's rotation covers a distance of 1 DEGREE longitude in 4 min. India has a longitudinal extent of 30 from Arunachal Pradesh(east) to Gujarat(WEST).It accounts for a time difference of 2 hours.So,the Sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat. To avoid confusion due to time dfferences and to have a STANDARD time for REFERENCE,the time along the meridian 82 degree 30 minE passing near Allahabad in U.P has been taken as the standard time for the entire country.That is why the clock shows the same time.
