From which place in Uttar Pradesh does the Standard Meridian of India pass?
A)Kanpur
B)Mirzapur
C)Allahabad
D)Lucknow

Hint :Standard Meridian is the meridian used for calculating standard time.It is generally selected in multiples of 7°30' of longitude for any country. The city through which the Standard Meridian of India passes is famous for its carpets and brassware industries.


Complete answer :
The 82°30’E longitude is taken as Standard Time Meridian of India, and it passes through Mirzapur in Uttar Pradesh. The city is famous for its carpets and brassware industries.
India has a vast longitudinal extent and a number of meridians pass through it. Hence, it is important to adopt the local time of one central meridian as the standard time for the country. Thus, we require a standard meridian for the country.
82°30' E has been chosen as the Standard Meridian of India because it is located in the centre of all longitudes in which our country is located. A standard meridian is established in each country so that it is the central longitude of the whole country and there is an equal time throughout the country.

Option B,is the correct answer.

Note :
In India the North-South extent is longer than the East-West due to the following reasons:
The distance between latitudes remains the same throughout that is 111 km but the distance between the two longitudes is 111 km at the equator which reduces to 0 at the poles.
In other words, we can say that India’s north-south extent and distance remains unchanged.

Due to a decrease in the distance between the two longitudes, the east-west extension has a U shaped bending which actually reduces the actual east-west distance. Hence, the longitudinal lines come closer and the East-West distance becomes less than the North-South distance.
