the gravitational force of attraction=GMm/r²
=6.67×10^-11×10×10/(10/100)²
=6.67×10^-11×10^2/(1/10)²
=6.67×2×10^-11+2/1/100
=6.67×2×10^-9×10^2
=6.67×2×10^-9+2
=6.67×10^-7N kg²/m²

Answer:
From the formula , F=G Mm/R2
G= Gravitational constant=G
M=m= mass of each of the spherical balls=10kg
R=distance between the balls = 10cm = 10/100 m =10-1m
>F= G× 10²/10-² = G × 10²–(²)=G×10⁴
>Gravitational force of attraction between the spherical balls =10⁴G Newtons.
