Question

Which one of the cities never experiences vertical rays of the sun during noon?
A. Chennai
B. Mangalore
C. Mumbai
D. New Delhi

Answer 1

Hint: It is a line that determines which of the Indian states will get the vertical rays. The vertical rays of the sun will hit only those states which lie to the north of the Tropic of Cancer.

Complete answer: The most northerly circle of latitude on the earth is known as the Tropic of Cancer. It is also known as the Northern Tropic. At the Tropic of Cancer, the sun can be directly overhead.
According to the Georgian calendar, the solstice that occurs each year between June 20 to 22 is known as June Solstice.
The June solstice in the northern hemisphere is known as the summer solstice and the December solstice in the southern hemisphere is known as the winter solstice.
When the sun is overhead on the tropic of Cancer (23.5 degrees), on June 21, then the pressure belt shifts 5 degrees northwards and the vertical rays strikes the north of the equator and then migrates, and on December 22, when the sun shines overhead on the Tropic of Capricorn (23.5 degrees), the pressure belt shifts 5 degrees southwards and the vertical rays strikes the south of the equator and then migrates.
While talking about the options,
D.out of the given states except for New Delhi, all Chennai, Mangalore, Mumbai falls lies to the south of the Tropic of Cancer. Therefore, as New Delhi lies to the north, it never gets the vertical rays of the sun.

Thus the correct option is D.

Note: Through Gujarat, Rajasthan, Madhya Pradesh, Jharkhand, Chattisgarh, Tripura, Mizoram, and West Bengal the line of Tropic of Cancer passes.
