• A. Continue to move with same speed along a straight line tangentially to the satellite at that time
• B. Continue to move with same speed along the original orbit of satellite
• C. Fall down to earth gradually
• D. Go far away in space

The orbital speed of a satellite is independent of mass of a satellite, so ball will behave as a satellite and

will continue to move with same speed in original orbit.
