Answer:
when the radius is halved, F becomes 4 times
Explanation:
The formula is given by
[tex]F = \frac{Gm1m2}{r^2}[/tex]
When r is halved:
[tex]F = \frac{Gm1m2}{(1/2r)^2}[/tex]
=> [tex]F = \frac{Gm1m2}{1/4 r^2}[/tex]
=> [tex]F = 4(\frac{Gm1m2}{r^2} )[/tex]
This means when the radius is halved, F becomes 4 times
