Question

1) Why has 82030" E selected as standard meredian of
Inded?​

Answer 1

Answer:

82°30' E has been selected as the Standard Meridian of India because it is situated in the centre of all longitudes and latitudes in which our country is located. ... The local times which lie on different meridians are bound to differ. The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat

Answer 2

ANSWER:

• This meredian is is the centre most longitude of India, which creates a equal time difference between the western most and the eastern most points of India. It means from the standard meredian to Arunachal Pradesh, the time difference is 1 hour and similarly, from the standard meredian from Gujarat, the time difference is again 1 hour.(Leading to total difference of two hours from gujarat to arunachal pradesh.)

• Due to vast longitudanal extent, there might be confusion in country if we start following the local times. So in order to avoid this confusion, 82030'E is taken as stndard meredian of India.

• As per the international norms the standerd meredian should be divisble by 15 or 7.5. Since, along with fulfiling all the other 82030'E is also divisble by 7.5, therefore it is selected as standard meredian of the country
