## anonymous one year ago A new solar system with two planets of equal mass - Planet X and Planet Y - is discovered. Planet X is closest to the sun. What is the sun's gravitational pull on Planet Y as compared with Planet X? A. The sun's gravitational pull on Planet Y is equal to its gravitational pull on Planet X because distance does not affect the sun's gravity. B. Because Planet Y is farther from the sun, the sun's gravitational pull on Planet Y is less than the sun's gravitational pull on Planet X. C. The sun's gravity repels Planet Y with more force than it repels Planet X,

hold on

$F=G \frac{ M1*M2 }{ d^{2} }$ Do you understand this formula?

force of gravity always depends on the mass and the distance of two objects. according to Newton's universal gravitation, the force of gravity to the product of the masses is directly proportional and inversely proportional to the square of distance between them. Therefore, since planet Y is farther than planet x, it should have a lesser force of attraction with the sun :)

So a?

^ This is it. The mathematical formulation is just in my post. And it's not a, because distance AFFECTs gravitational pull.

its b
