Q. What will happen to a ball if it is dropped from a spacecraft revolving around the earth at a height of 120 km?
✅ Correct Answer: (D)
It will continue to move with velocity v along the original orbit of spacecraft
Explanation: If a ball is dropped from a spacecraft revolving around the earth at a height of 120 km, it will continue to move with velocity v along the original orbit of spacecraft. As the ball possess same initial tangential speed as that of space craft. So, it also feels the condition of weightlessness.
