Question

To overcome the effect weightlessness in an artificial satellite

• A. the satellite is rotated around its axis with compartment of astronaut at the centre of the satellite.
• B. the satellite is shaped like wheel.
• C. the satellite is rotated around and around till weightlessness disappears.
• D. the compartment of astronaut is kept on the periphery of rotating wheel like satellite.

Answer 1

Answer: (D)

the compartment of astronaut is kept on the periphery of rotating wheel like satellite.

On a rotating body, as we move away from center of rotation the centrifugal force increases. So, the centrifugal force is maximum at the periphery of a rotating wheel. Thus, having the astronaut room there would solve some of the weightlessness problem in satellite.
