Odpowiedź :
F = Gm1m2/r²
r = 1km = 1000m
m1 = m2 = 1kg
G = 6,67 * 10^-11 Nm²/kg²
F = 6,67 * 10^-11 Nm²/kg² * 1kg * 1kg / (1000m)² = 6,67 * 10^-11 N/1000000 = 6,67 * 10^-11 N / 10^-6 = 6,67 * 10^-5 N
r = 1km = 1000m
m1 = m2 = 1kg
G = 6,67 * 10^-11 Nm²/kg²
F = 6,67 * 10^-11 Nm²/kg² * 1kg * 1kg / (1000m)² = 6,67 * 10^-11 N/1000000 = 6,67 * 10^-11 N / 10^-6 = 6,67 * 10^-5 N
