At what distance will the force of attraction between two bodies weighing 1000 kg

At what distance will the force of attraction between two bodies weighing 1000 kg each be equal to 6.67 • 10-9 N? The constant of world gravity is equal to 6.67 • 10-11 N • m² / kg².

The force of gravitational attraction between two bodies of masses m1 and m2, located at a distance R from each other, is determined from the formula:
F = G * m1 * m2 / (R ^ 2);
F = 6.67 * 10 ^ (- 9)
m1 = m2 = 1000
G = 6.67 * 10 ^ (- 11) H * (m ^ 2) / (kg ^ 2);
R = √ (G * m1 * m2 / F) = m1 * √ (G / F);
R = 1000 * √ (0.01) = 100m.
