Question

No part of India is situated on the equator. Is it possible to have a geostationary satellite which always remains over New Delhi?

Answer 1

Hint: We can decide whether or not there will be a geostationary satellite above a given place by comparing its location with respect to the equator as a geostationary satellite always orbits above the equator.

Complete step-by-step answer:
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers over the equator, that revolves in the same direction the earth rotates (west to east).
New Delhi, is 28 degrees north to the position of the equator,
Hence it is not possible to have a geostationary satellite directly over Delhi.

Additional Information:
The equator is a pseudo line drawn on the earth equidistant from the two poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0°.
There are two poles North pole and South pole, North pole lies in the northern hemisphere of the earth, whereas South pole lies in the southern hemisphere.
The earth is divided into two hemispheres, the Northern hemisphere constituting countries like India, Pakistan, Mexico, Switzerland, United Kingdom, Russia, Spain, Sweden, Romania, Spain. And the southern hemisphere constituting Indonesia, Brazil, East Timor, Australia, and South Africa.
The Tropic of Capricorn and Cancer are two more lines drawn because they are both places within the two hemispheres where it's possible for the sun to be directly overhead. And for the ancient travelers who used the heavens to guide their way, these were crucial demarcation lines.

Note: No geostationary satellite ever revolves outside the equator.
However, they can keep an eye on the countries that are slightly off from equator
