Question

given the following formula, solve for r.

Answer 1

it should be c if the subscript g is a factor as well

Answer 2

Answer: Hello mate!

The formula is  $F = G\frac{m1*m2}{r^{2} }$

and we want to solve it for r, which means that we need to isolate r.

The first step is multiply both sides by r squared:

$r^{2}*F = G*m1*m2$

now we divide both sides by F

$r^{2} =G\frac{m1*m2}{F}$

now we aply square root in both sides:

$\sqrt{ r^{2} } = r = \sqrt{G\frac{m1*m2}{F} }$

And now you have r isolated.

Then the right answer is option C.
