Imagine an astronaut inside a satellite ...

Imagine an astronaut inside a satellite going around the earth in a circular orbit at a speed of `sqrt((gR)/(2))` where R is radius of the earth and g is acceleration due to gravity on the surface of the earth. What is weight experienced by the astronaut inside the satellite? Assume that an alien demon stops the satellite and holds it at rest. What is eight experienced by the astronaut now? The demon now releases the satellite (from rest). What is weight experienced by the astronaut now?
