A ball is dropped from a spacecraft revolving around the earth at a height of (120 ~km ). What will happen to the ball ?
Options
- AIt will continue to move with same speed along the original orbit of spacecraft
- BIt will move with the same speed tangentially to the original orbit
- CIt will fall down to the earth gradually
- DIt will go very far in space
Correct answer
A. It will continue to move with same speed along the original orbit of spacecraft
Step-by-step solution
When ball is dropped from a spacecraft revolving around the earth at a height (120 ~km ), then speed of ball is same as speed of spacecraft because orbit of ball is same as spacecraft, hence it will continue to move with same speed along the original orbit of spacecraft.
