Assume you are sent in a satellite.
A) Find how far above the surface of the earth, you would lose 1/2 of your weight?
B) To maintain the satellite orbiting around the earth at that distance, evaluate what would be the velocity of the satellite?
C) Suppose you have takenw\a weighing machine with you. If you try to measure your weight using the weighing machine, determine what will be your weight? [The satellite orbits around the earth like in case B.]
