Question

The gravitational force between two asteroids 1200 km apart is 8400 N. Find the following changes in gravity (do not write units)

a) What is the force between them if the distance is 600 km?

Answer 1

F = k/d^2
so
k = F d^2

8400 (1200)^2 = F ( 600)^2

F = 8400 (2)^2 = 8400 * 4

Answer 2

Thanks SOOO much
