Vedclass · Answer

(C) Inside an artificial satellite,both the satellite and the man are in a state of free fall towards the Earth. The gravitational force exerted by the Earth on the man provides the necessary centripetal force required for his circular motion in orbit. Since the man and the satellite are accelerating at the same rate towards the Earth,the normal reaction force exerted by the floor of the satellite on the man is zero. This state is perceived as weightlessness. Therefore,the gravitational force is equal to the centripetal force required for the orbit.

$A$ man inside an artificial satellite feels weightlessness because the force of attraction due to the Earth is
