Weightlessness in orbit is due to the continuous freefall of the satellite and its occupants. The gravitational force is not zero; instead, it provides the centripetal acceleration necessary for orbital motion. The sensation of weight arises from the normal force exerted by a supporting surface, which is absent in freefall.
A man inside an artificial satellite feels weightlessness because the force of attraction due to earth is - A) Balanced due to force of attraction due to moon - B) Zero - C) Equal to centrifugal force - D) Non-effective due to solar radiation
