Answer:
Correct Answer: C
Solution:
A person feels his weight only when the surface on which he is standing exerts a reactionary force on him. Because the acceleration of the person and that of the satellite revolving round the earth are equal (= g), hence acceleration of the person with respect to the satellite is zero. Therefore person feels weightless on satellite, although the gravitational force is acting on a satellite.
