1.16 x 10⁻⁸N

Explanation:

Given parameters:

Mass of the two asteroids  = 50000kg

Distance between the asteroids  = 3800m

Unknown:

Gravitational force between the two asteroids = ?

Solution:

To solve this problem, we apply the newton's law of universal gravitation:

  Fg  = \frac{G mass 1 x mass 2}{r^{2} }  

 G is the universal gravitation constant

 r is the distance between them

So;

       Fg  = \frac{6.67 x 10^{-11}  x 50000 x 50000}{3800^{2} }   = 1.16 x 10⁻⁸N

gases have lots of energy and have very little forces of attraction

-they move at high speeds

-they move freely in all directions

-they move constantly

-they are far apart (unless they bump into each other lol)
