Lực hấp dẫn giữa hai vật có khối lượng 5kg và 7kg và cách nhau 10m là bao nhiêu?
The gravitational force between two objects with masses of 5kg and 7kg and a distance of 10m between them is:

F = G x (m1 x m2)/r^2

where:

F = gravitational force
G = gravitational constant (6.67 x 10^-11 N.m^2/kg^2)
m1 = mass of object 1 (5kg)
m2 = mass of object 2 (7kg)
r = distance between the two objects (10m)

Plugging in the numbers:

F = 6.67 x 10^-11 x (5 x 7) / 10^2
F = 2.335 x 10^-11 N

Therefore, the gravitational force between the two objects is approximately 2.335 x 10^-11 N.<|end_of_text|>
