    If suddenly the gravitational force of attraction between the earth and a satellite revolving around it becomes zero, what will happen?

    A)  The satellite will continue to move in its orbit with the same velocity.

    B)  The satellite will move tangentially and escape away from its orbit.  

    C)  The satellite will become stationary in its orbit.

    D)  The satellite will move towards the earth.

    Correct Answer: B

    Solution :

     When gravitational force becomes zero, then centripetal force on the satellite also becomes zero. Therefore, the satellite moves tangentially and escapes away from its orbit.
