Answer
India and the USA are on opposite sides of the spinning Earth.

Explanation

  • The Earth's rotation lights only one half at a time.
  • India and the USA are on nearly opposite sides.
  • When India faces the Sun, it is day there.
  • At the same time, the USA is in darkness, so it is night.
Opposite sides of the Earth have day and night at the same time.
