13. which of the following pairs of objects would have the greatest attraction toward each other due to gravity?
a. a 10 kg object and a 10 kg object,
4 m apart
b. a 5 kg object and a 5 kg object,
4 m apart
c. a 10 kg object and a 10 kg object,
2 m apart
d. a 5 kg object and a 5 kg object,
2 m apart

c

Explanation:

First calculate  gravitational force between objects

a) Fg=γ*m1m2/r²

m1=m2=10kg

r=4m

Fg=γ* 100kg²/16m²

Fg=6.25γ

b)Fg=γ*m1m2/r²

m1=m2=5kg

r=4m

Fg=γ*25m²/16m²

Fg=γ*1.56

c)m1=m2=10kg

r=2m

Fg=γ100kg²/4m²

Fg=γ25

d)m1=m2=5kg

r=2m

Fg= γ25kg²/4kg

Fg=γ6.25

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

pretty sure it's false
