If suddenly the gravitational force of attraction between Earth and a satellite revolving around it becomes zero, then the satellite will
  1. continue to move in its orbit with same velocity
  2. move tangentially to the originally orbit in the same velocity
  3. become stationary in its orbit
  4. move towards the earth.

Solution

When gravitational force becomes zero so centripetal force on satellite becomes zero so satellite will escape its round orbit and moves tangentially with same velocity.
