The artificial gravity is created in the satellite to:
Correct answer: D. Overcome the weightlessness experienced by astronaut
- A. Increase the orbital speed of the satellite
- B. Keep the satellite in its orbit
- C. Keep the orbital radius of the satellite constant
- D. Overcome the weightlessness experienced by astronaut
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.

Weight rather than mass must be used when calculating:
A body of mass m is projected from the earth's surface at the point of launch, the acceleration of free fall is g and the radius of earth is Re. To escape from the gravitational field of the earth, the speed of the body (i.e. escape velocity) must be at least:
Assuming the earth to be a uniform sphere rotating about an axis through the poles, the weight of a body at equator compared with its weight at the pole would be:
