Answer:
e) Be four times greater
Explanation:
Here we have to use Newton's gravitational law that relates the gravitational force between two objects with their masses (
& 
) and the distance between them (
) in the next way:
(2)
Now if distance between asteroids is halved:
Note that 
because (1) is F so:
It's four times greater!
