The artificial gravity is created in a satellite to overcome the state of weightlessness, experienced by the astronauts in it, by:
Correct answer: C. Causing the satellite to rotate about its own axis
- A. Decreasing the orbital speed of the satellite
- B. In creasing the orbital speed of the satellite
- C. Causing the satellite to rotate about its own axis
- D. None of the above
Explanation
Artificial gravity in a satellite to overcome the state of weightlessness experienced by astronauts can be achieved by creating centripetal acceleration through the rotation of the satellite. This involves spinning the satellite, generating centrifugal force, and simulating gravity for objects and astronauts inside. The formula for centripetal acceleration (\(a_c\)) is used to determine the necessary rotational parameters, and adjusting the rotation rate and radius of rotation can create artificial gravity equivalent to Earth's gravity.

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.
