See below

Explanation:

Following Newton's gravity law, we know that the gravitational force between 2 masses separated by a distance d is
$F = G \frac{M m}{d^{2}}$ $F=G(Mm)/d^2$ where G is a constant valued aprox. $6.674 \cdot 10^{- 11} N \frac{m^{2}}{k^{2}}$ $6.674 ·10^-11Nm^2/k^2$

Substituting:

$F = 6.674 \cdot 10^{- 11} \cdot \frac{100 \cdot 100}{10^{2}} = 100 G = 667.4 \cdot 10^{- 11} N \frac{m^{2}}{k^{2}} = 6.674 \cdot 10^{- 9} N \frac{m^{2}}{k^{2}}$ $F= 6.674 ·10^-11·(100·100)/10^2= 100 G = 667.4 ·10^-11Nm^2/k^2=6.674 · 10^-9Nm^2/k^2$
