Two new planets with equal masses are discovered. planet "a" is twice as far from the sun as planet "b." which of the following is true.
a.) the gravitational pulls between the sun and each of the planets are the same because the masses of the planets are the same.
b.) the gravitational pulls between planet "a" and the sun is smaller than the gravitational pull between planet "b" and the sun.
c.) the suns gravitational pull on planet "a" is equal to its to its gravitational pull on planet "b" because distance does not effect gravity.
d.) the sun will attract planet "b" and repel planet "a"
