Which of the following are true?
  • A
    A polar satellite goes around the earth’s pole in northsouth direction.
  • B
    A geostationary satellite goes around the earth in eastwest direction.
  • C
    A geostationary satellite goes around the earth in westeast direction.
  • D
    A polar satellite goes around the earth in eastwest direction.
✓

Answer

  1. A polar satellite goes around the earth’s pole in northsouth direction.
  1. A geostationary satellite goes around the earth in westeast direction.

Explanition:

The satellite which appears stationary relative to earth is called the geostationary satellite. It revolves around the earth in the west-east direction with the same angular velocity as done by the earth about its own axis in the west-east direction. A polar satellite revolves around the earth's pole in north-south direction. It is independent of earth's rotation. Option (a), (c) are correct.
