The mass of Planet X is one tenth that of the Earth, and its radius is one half that of the Earth. The acceleration due to gravity at the surface of Planet X is most nearly: (A) 2m/s2 (B) 4m/s2 (C) 5m/s2 (D) 7 m/s2 (E) 10 m/s2

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
