Whenever two Apollo astronauts were on the surface of the Moon, a third astronaut orbited the Moon. Assume the orbit to be circular and 360 km above the surface of the Moon, where the acceleration due to gravity is 1.16 m/s2. The radius of the Moon is 1.70 106 m.
(a) Determine the astronaut's orbital speed.m/s
(b) Determine the period of the orbit.s
List and explain briefly similarities and differences between the electric force between two charges and the gravitational force between two masses.
