Question

Imagine a new planet is discovered with two moons of equal mass: Moon A and Moon B.

The mass of the new planet is greater than the combined mass of its moons.

Moon A is farther away from the new planet than Moon B.

What is the planet's gravitational pull on Moon A compared to the planet's gravitational pull on Moon B?

A.
The gravitational pull on Moon B is greater than on Moon A because Moon B is closer to the new planet than Moon A.

B.
The gravitational pull on Moon B is greater than on Moon A because Moon B is farther away from the new planet than Moon A.

Answer 1

C.
The gravitational pull on Moon A is the same as the gravitational pull on Moon B because distance does not affect the planet's gravity.

D.
The planet's gravity repels Moon A with a greater force than it repels Moon B, which is why Moon A is farther away.

Answer 2

A. Kepler's law states that the gravitational pull is dependent on the inverse square of the distance. So the farther away a body is the smaller the gravitational force is.

Answer 3

the answer is a. mathematically, to solve for gravitational force , we have that;
\[F=\frac{ Gm _{1}m _{2} }{ r ^{2} }\]
from this, we have that gravitational force F is inversely proportional to the square of distance between the planet and a moon (r)

Answer 4

so B?

Answer 5

check if B tallies with Kepler's law

Answer 6

im not good at physics so im not really sure @Bowate

Answer 7

you can be good at it. just imagine the planet as a guy and the moons as two girls. the guy likes the two of them but he has a greater attraction to girl B. He seems to be closer to B than A because there is a greater attraction between the guy and girl B. it's the same with planets. the closer a moon to the planet, the greater the gravitational force.

Answer 8

its C
