In order to find time, the astronaut orbiting in an earth satellite should use

Earth orbiting satellite will escape if

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?
