Read the following statements carefully and indicate all the correct answers.

True False  An object weighing 100 N on Earth would weigh 400 N on a hypothetical planet with the same mass as Earth's but half its radius.
True False  If one were to double the mass of an object, its gravitational potential energy near any planet would double.
True False  The gravitational pull of Earth on an object is independent of how high the object is above the Earth's surface.
True False  It is possible to shield the gravitational pull between two bodies by placing a third object in between.
True False  If the distance between two objects doubles, the force of gravitational attraction between them will double as well.
