JEE MAIN - Physics (2002 - No. 69)
If suddenly the gravitational force of attraction between Earth and a satellite revolving around it becomes zero, then the satellite will
continue to move in its orbit with same velocity
move tangentially to the original orbit with the same velocity
become stationary in its orbit
move towards the earth
설명
When gravitational force of attraction between Earth and a satellite revolving around it becomes zero, then the centripetal force becomes zero. So the satellite will move tangentially to the original orbit with the same velocity as it has at the instant when gravitational force becomes zero.
