    1. continue to move with same speed along a straight  line tangentially to the satellite at that time ​
    2. continue to move with the same speed along the original orbit of satellite
    3. fall down to earth gradually ​
    4. go far away in space
Correct Option: B

The orbital speed of satellite is independent of mass of satellite, so the ball will behave as a satellite and will continue to move with the same speed in the original orbit.
