How the artificial gravity is created in a satellite to overcome the state of weightlessness experienced by the astronaut in it?
Correct answer: D. By causing the satellite to spin about its own axis
- A. By increasing the orbital speed of the satellite
- B. By decreasing the orbital speed of satellite
- C. By keeping the orbital speed of the satellite constant equal to that of the earth's around sun
- D. By causing the satellite to spin about its own axis
Explanation
Artificial gravity in a spaceship can be created using the principle of centripetal force. This force is generated by the rotation of the spaceship. When a spaceship rotates, it creates a centrifugal force that pushes objects inside the spaceship outward, away from the axis of rotation. This outward force acts as if it were a gravitational force, creating a sense of gravity for the occupants inside.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
