उत्तर

  1. Launching of a satellite in an orbit around the Earth cannot take place by the use of a single-stage rocket. It requires a minimum of two stage rocket.
  2. With the help of the first stage of the rocket, satellite can be taken to the desired height above the surface of the Earth.
  3. Then the launcher is rotated in a horizontal direction i.e., through 90° using the remote control and the first stage of the rocket is detached.
  4. With the help of the second stage of the rocket, a specific horizontal velocity (vh) is given to the satellite so that it can revolve in a circular path around the Earth.
  5. The satellite follows different paths depending upon the horizontal velocity provided to it.
