Question

What is the gravitational force of attraction between two asteroids in space, each with a mass of 50,000 kg, separated

Answer 1

Answer:

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
