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(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(m1*m2)/(F)`

now we aply square root in both sides:

`\sqrt{ r^(2) } = r = \sqrt{G(m1*m2)/(F) }`

And now you have r isolated.

Then the right answer is option C.
