Question

Exercise 1: NEWTON'S UNIVERSAL LAW OF GRAVITY
F=Gm1m2/r^2
In terms of G, and using SI units, what is the formula? I have an attatchment

Answer 1

Rearrange the equation in terms of G.

Answer 2

I know, im having a hard time with that. I think it is G=m^3/s^2*kg???

Answer 3

\[F = G \frac{ m_1 m_2 }{ r^2 } \implies G = \frac{ Fr^2 }{ m_1 m_2}\] I leave the rest to you :)
