Question

explain why Ahmedabad and Kolkata are able to see the noon Sun exactly overhead in a year but not Delhi

Answer 1

Answer:

Ahmedabad has latitude 23 N and Kolkata 22.5 N , while Delhi is at latitude 28 N . this means that the first two cities lie within the tropic of cancer. the tropic of cancer is the circle of latitude on the earth that marks the apparent position of the sun at the time of the northern solstice. it is also the farthest north latitude at which the sun can be directly overhead. so in Delhi, the sun is never directly overhead .
