Ответ: 3,8*10⁻¹⁰Н

Объяснение:

Дано:

m1=12т=12000кг

m2=12т=12000кг

r=5км=5000м

G = 6,67*10⁻¹¹ Н*м2 / кг2

-----------------------

F-?

Согласно закона всемирного тяготения:

F=G*m1*m2/r², где:

G-гравитационная постоянная;

m1-масса первого тела;

m2-масса второго тела;

r-расстояние между телами

F=6,67*10⁻¹¹*12000*12000/5000²=3,8*10⁻¹⁰Н
