At which of the following places can one not see the midday sun exactly overhead twice a year?

Correct answer: (b) Sagar (Madhya Pradesh)

Explanation

The midday sun is exactly overhead twice a year only at places between the Tropics (23½° N and 23½° S). The Tropic of Cancer (about 23.44° N) passes through Madhya Pradesh, close to these places:

• Sagar (about 23.8° N) lies north of the Tropic, so the sun is never exactly overhead there;
• Ranchi (about 23.3° N), Gandhinagar (about 23.2° N) and Jabalpur (about 23.2° N) lie just south of it, so the sun is overhead twice a year, in June, just before and after the summer solstice.
