Question

PLEASE HELP!

Answer 1

Inverse: Flipping the fraction of a number. For example the inverse of 2 would be 1/2. So force/1 has to = x/radius^2

Find "x":
 $F_{gravity} = \frac{x}{r^2}$
Plug in numbers given:
 $F_{gravity} = \frac{x}{r^2}$
$600= \frac{x}{(4,000)^2}$
$600= \frac{x}{16,000,000}$
$x=9,600,000,000$

Find Force using x and the new radius:
 $F_{gravity} = \frac{x}{r^2}$
 $F_{gravity} = \frac{9,600,000,000}{(240,000)^2}$ = 1/6
