To solve this problem, we use the formula:
F = G m1 m2 / r^2
where F is gravitational force, G is constant, m1 and m2
are masses while r is the distance between the two asteroids
Since G m1 m2 is constant, therefore:
F1 r1^2 = F2 r2^2
So if r2 = 2 r1:
(1,000,000 N) (r1^2) = F2 * (2 r1)^2
<span>F2 = 250,000 N</span>

Explanation:
The nearest star to the Earth is the red dwarf star Proxima Centauri, at a distance of 4.218 light-years.
Light year is the unit of distance covered by the heavenly bodies. 1 light year is equal to :
So, 
We need to convert 4.218 light-years barley corns.
Since, 1 barleycorn = 1/3 inch
So, the nearest star to the Earth is at a distance of 
. Hence, this is the required solution.
Hello!
Use the formula:
W = Fd
Replacing:
W = 300 N * 300 m
Resolving:
W = 90000 J
The work is <u>90000 Joules.</u>
