Which one among the following cities never get the vertical rays of the Sun all through the year ?
Explanation
The mid-day sun is exactly overhead at least once a year on all latitudes between the Tropic of Cancer (23.5° N) and the Tropic of Capricorn (23.5° S) [2]. This region, known as the torrid zone, receives vertical rays as the subsolar point migrates between these two parallels throughout the year [5]. Beyond the Tropic of Cancer, the sun's rays are always slanted, and the mid-day sun never shines directly overhead [3]. Geographically, Chennai (13° N), Mumbai (19° N), and Kolkata (22.6° N) all lie south of the Tropic of Cancer, meaning they receive vertical rays twice a year. In contrast, Srinagar is located at approximately 34° N, which is well north of the Tropic of Cancer [2]. Consequently, Srinagar never experiences the vertical rays of the Sun at any time during the year.
