Question

F = Gm^2/r^2 .

solve for G

Answer 1

Answer 2

What have you done so far?

Answer 3

so i know that you have take the MULTIPLY the r^2 to both sides so now i'm left with Fr^2 =Gm^2 but i don't know what else to do

Answer 4

so maybe its G= Fr^2/m^2 ?

Answer 5

or is it Fm^2/ r^2

Answer 6

What you could do with multiply could be done with divide as well.
Fr^2=Gm^2
So there you are, dividing both sides by m^2 gives
Fr^2/m^2=G
or
G=Fr^2/m^2

Answer 7

i'm so confused.

so from F = Gm^2/r^2 . why wouldn't you multiply m^25 to both sides to get Fm^
2 = G/r^2 , and then do the same with r^2 GIVING YOU Fm^2/r^2

@word2

When we say solve for G we mean that we have to get G by itself

\[F = \frac{ G~m^{2} }{ r^{2} }\]

the first thing we need to do is multiply both sides by r^2

\[F*(r^{2}) = \frac{ G~m^{2} }{ \cancel\r^{2} }*(\cancel\r^{2})\]

\[F*(r^{2}) = G~m^{2}\]

What do you think you should do now?

Answer 9

take out the G, so divide it to the other side
