Question

If suddenly the gravitational force of attraction between Earth and a satellite revolving around it becomes zero, then the satellite will-

A. continue to move in its orbit with same velocity
B. move tangentially to the original orbit in the same velocity  
C. become stationary in its orbit
D. move towards the earth
Answer :   move tangentially to the original orbit in the same velocity
Solution :
Due to inertia of motion it will move tangentially to the original orbit in the same velocity.
