Question

I have honestly no clue how to do this plz help me

Answer 1

Answer:

$M_{2} = \frac{r^{2} F_{g} }{GM_{1}}$

Step-by-step explanation:

$\frac{GM_{1} M_{2}}{r^{2}}=F_{g}$

Multiply both sides by (r²)....  $GM_{1} M_{2}=r^{2} F_{g}$

Divide both sides by (GM₁).... $M_{2} = \frac{r^{2} F_{g} }{GM_{1}}$
