In a spaceship, artificial gravity is created with the help of:
Correct answer: B. Centrifugal force
- A. Centripetal force
- B. Centrifugal force
- C. Magnetic force
- D. None of the above
Explanation
Correct Answer: B 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. The formula for centripetal force (Fc) is given by: Fc =m⋅v2/r In the case of a rotating spaceship, the floor of the spaceship acts as the "ground," and the centrifugal force experienced by objects on the floor provides a sense of gravity. The greater the rotation speed or the larger the radius of rotation, the stronger the artificial gravity effect.

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.
