Jessie James · Answer 1

Answer: 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
