a) What is the rotational angular velocity of an Elidium
required to have the same gravitational acceleration as Earth in an
elidium Outside the Earth with a radius of 10 km and a mass of
10^9 kg (=10^6 tons)?
(However, the gravity of other celestial bodies is not taken
into account. The Earth has a radius of 6,400km and a mass of 59.8
trillion ton)
b) How much energy per second is required for the above
rotational motion?
c) What is the most appropriate way to obtain the above
energy?
(Choose one of the nuclear plant, solar farm, and oil of coral
plant.)
