The following diagrams show five pairs of asteroids, labeled with their relative masses (M) and distances (d) between them. For example, an asteroid with M=2 has twice the mass of one with M=1 and a distance of d=2 is twice as large as a distance of d=1. Rank each pair from left to right based on the strength of the gravitational force attracting the asteroids to each other, from strongest to weakest.
M = 1, D = 2, M = 1.
M = 1, D = 2, M = 2.
M = 1, D = 1, M = 1.
M = 1, D = 1, M = 2.
M = 2, D = 1, M = 2.
(1.) M = 2, D = 1, M = 2.
(2.) M = 1, D = 1, M = 2.
(3.) M = 1, D = 1, M = 1.
(4.) M = 1, D = 2, M = 2.
(5.) M = 1, D = 2, M = 1.
Correct.
You have correctly taken into account both the masses of the asteroids and the distances between them.
