A particle smaller than an atom or a <span>cluster of such particles </span>
Answer:
2 or 3
Explanation:
2 or 3 look exactly the same to me.
<span>as i recall, gravity is relative to the square of the distance.
so if the distance is tripled, then the gravitational attraction would be reduced by 3^2 or 1/9.
so F1 = F0/9
if the satellite is 2R from the center, and is moved to 4R (doubled would be 3R, tripled is 4R) then the distance is twice, and gravity would be 2^2 or 1/4.
