Question

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,

Answer 2

For gravitational force:
\[F = \frac{Gm_{1}m_{2}}{r^2}\]
Where 'G' is the universal gravitational constant, m1 and m2 are the masses of two bodies, and 'r' is the distance between the two masses.

Answer 3

As you can see, gravitational force is inversely proportional to the distance between two masses. So, as the distance decreases, the force between them increases.

Answer 4

so the answer is a?

Answer 5

Why would it be A? I also said distance affects gravitational force.

Answer 6

oh yeah your right sorry

Answer 7

im not really sure :(

Answer 8

Look at Choice B. Does this go with my explanation about distance and force? As the distance between two objects increase, the gravitational force between them decreases.

Answer 9

Thanks!
